Title

Innovation in Low-Carbon Bio-Based Construction Technologies

Abstract

Human beings have thrived on Earth and constructed numerous habitats for survival. From primitive, simple shelters built in ancient times for protection against wind and rain, to modern reinforced concrete structures like skyscrapers and high-speed railways, civil engineering construction technologies have undergone epochal evolutions. Amid global climate change and ecological degradation, the drawbacks of traditional engineering construction, such as high energy consumption, high emissions, heavy pollution, and poor degradability of solid waste materials, have severely hindered the implementation of the dual-carbon development strategy and the advancement of construction technologies, transforming civil engineering construction into an urgent imperative. To achieve sustainable development, civil engineering must minimize the depletion and damage of natural resources. Aligned with China’s dual-carbon strategic goals, the global frontier of biotechnology, and the transformative development of the construction industry, bio-based construction is proposed as an approach that enables harmonious coexistence between humans and nature in line with the dual-carbon strategy. It is grounded in scientifically based planning and design, aiming to integrate engineering projects with surrounding ecological environments and preserve the integrity and stability of ecosystems. This report elaborates on the connotation of bio-based construction, establishes its technical system, and systematically discusses its theories, technologies, materials, equipment, and engineering applications across four categories: microbial construction, plant-based construction, animal-derived construction, and bionic construction. Finally, the development prospects of the bio-based construction discipline and industry are discussed.

Mechanism and Numerical Prediction of Port Resonance Disasters Induced by Medium- and Long-Period Waves

Abstract

Port resonance refers to the phenomenon of significant water oscillations within a harbor basin when the incident long-period waves from the open sea are close to the natural period of the harbor. Such resonance can trigger severe motions of moored vessels, reduce operational efficiency, and, in severe cases, lead to accidents such as mooring line rupture, ship collision with wharves, and uncontrolled vessel drift, posing a substantial threat to port operation and safety. This report first presents physical model tests on multimode coupled resonance in regular rectangular harbors, revealing the energy evolution process among different resonance modes. Meanwhile, numerical simulations are conducted to validate the analytical theory of port resonance excited by shear currents, clarifying the characteristics of harbor oscillations under the combined action of shear currents and waves. Second, corresponding analytical theories are proposed for regular pentagonal, regular hexagonal, and elliptical harbors, providing a theoretical basis for resonance prediction in practical ports. In addition, a snowflake fractal harbor layout is developed to mitigate port resonance. Third, considering the variable water depth in real ports, analytical models of port resonance are established for sloping, hyperbolic cosine, and exponential topographies. It is found that the refraction effect induced by bathymetric variation can trigger transverse resonance. For deep-sea island and reef ports, an island-harbor coupled resonance theory is proposed. Finally, based on the impacts of practical port resonance disasters, future research directions are pointed out.

Title

An Efficient Calculation Method for Failure Probability of Open-Type Piled Wharves Based on Macroelement Method and Monte Carlo Sampling

Abstract

The upsizing of vessels contributes to the reduction of carbon emissions per container, while open deep-water wharves enable the berthing of large ships and eliminate sediment deposition issues. Given the threats posed by climate change, it is urgent to evaluate the failure probability of open wharves, especially piled wharves with members of low section stiffness, to identify vulnerable components that require toughness improvement. This study proposes an efficient calculation method using the macroelement method and Monte Carlo simulation to address this challenge. Environmental parameters are randomly sampled based on probability distributions, and structural responses under various loadings are rapidly computed via the macroelement method. The proposed method has been validated against experimental results and finite element analyses. Both local and global failure criteria are adopted for failure assessment, realizing automated evaluation of the failure probability of piled wharves. In addition, parametric studies are conducted to investigate the effects of pile dimensions, steel grade, and environmental factors on failure probability. The results show that the failure probability of open-type piled wharves decreases with the increase of steel grade, pile diameter, and wall thickness, among which wall thickness exhibits the most significant influence. Meanwhile, failure probability rises with increasing wave height, water depth, current velocity, and wind speed, but decreases with increasing wave period. Among these parameters, wave period shows the dominant effect, followed by wave height and then water depth. Through failure mode analysis of an engineering case, it is found that 86.9% of failures originate from pile members, mainly due to excessive von Mises stress (75.0%) and axial overloading (19.9%), demonstrating the necessity of strengthening, monitoring, and toughening for the pile foundation system of piled wharves.

Title

Research on Eco-Friendly Rock Breaking Technology and Equipment in Marine Environment

Abstract

This project closely aligns with four national strategies: building a maritime power, a transportation power, ecological civilization, and achieving self-reliance and strength in science and technology. It aims to address the urgent demand for non-blasting underwater rock removal in major projects such as port and waterway construction, as well as cross-sea transportation corridors.

The project has successfully tackled several core technical bottlenecks: insufficient theoretical support for non-blasting rock breaking due to unclear rock fragmentation mechanisms underwater, low efficiency of conventional technologies in breaking rocks exceeding 40 MPa unconfined compressive strength, difficulty controlling operation accuracy in 40-meter-deep water with high flow velocities, and the lack of effective non-blasting methods for ultra-hard rocks up to 200 MPa.

Through the whole-chain innovation of theoretical analysis – equipment development – engineering application, the project has achieved the following key outcomes:

Theoretical Breakthroughs: The impact fragmentation laws and damage evolution mechanisms of underwater rocks have been revealed, and a comprehensive evaluation model for rock breaking performance has been established.

Technical Innovations: High-precision direct excavation using grabs and high-frequency vibratory techniques for soft rock have been developed. An innovative bubble-type anti-pollution curtain system for dredging projects has been pioneered, which effectively controls suspended sediment diffusion.

Equipment Upgrading: Key difficulties in precise positioning and visualization in deep water (40 m) have been overcome. A precise positioning algorithm for hydraulic impact hammers and an intelligent sonar data processing system have been developed.

Innovative Construction Technology: An eco-friendly reef-clearing technology featuring coupled drilling, splitting, and chiseling has been created for the first time. A new series of Mn13 high-strength wear-resistant rock-breaking hammers has been developed, successfully solving the fragmentation problem of ultra-hard rocks up to 200 MPa.

In terms of standardization and academic achievements, the project has led the establishment of a complete industrial standard system, including one international standard, two national standards, and 5 industrial construction methods. Meanwhile, three academic monographs have been published, 20 SCI/EI-indexed papers released, and 16 invention patents authorized, forming a full-chain independent intellectual property system covering theory, equipment, technology and standards.

The project achievements have been successfully applied in nearly 20 major domestic and overseas projects, including the Shenzhen-Zhongshan Link, Xiamen-Jinmen Corridor, and Ghana Tema New Container Terminal Project, solving a series of world-class challenges in deep-water hard rock excavation and construction in ecologically sensitive areas.

By replacing traditional reef blasting, the project has realized coordinated development of engineering construction and ecological protection, strongly supporting the implementation of the four national strategies. It has not only generated remarkable economic benefits but also driven a historic leap of China’s marine rock treatment technology from a follower to a global leader, providing an advanced Chinese solution for underwater hard rock treatment worldwide.

Seismic Catastrophe Mechanism of Immersed Tube Tunnels in Liquefiable Sand Sites and Key Technologies for Foundation Reinforcement

Abstract

With the in-depth implementation of the “Transportation Power” strategy and the advancement of regional coordinated development strategies such as the "Yangtze River Delta Integration", undersea immersed tube tunnels have become important transportation links connecting coastal urban agglomerations. Sandy seabeds are widely distributed and prone to liquefaction under seismic action, leading to a decrease in foundation bearing capacity and inducing tunnel uplift, which poses challenges to engineering safety. Based on centrifuge shaking table tests and numerical simulations, this study systematically analyzes the seismic catastrophe mechanism of immersed tube tunnels in sandy sites under horizontal and bidirectional seismic actions, and studies the seismic reinforcement effects of different foundation treatment measures. The research results provide a scientific basis and reference for the seismic design of undersea immersed tube tunnels.

Title

Dynamic Catastrophe Mechanism of Large-Diameter Monopile Foundations for Offshore Wind Turbines in Complex Marine Environments

Abstract

Offshore wind power is an important field in the development of renewable energy. As the most commonly used form of offshore wind power, monopile wind turbines are characterized by large size (diameter > 7m), variable loads (wind-wave-current coupling), large unit loads, and complex geological conditions. Accurately grasping the deformation and failure mechanism of large monopile wind turbines under complex marine loads is a key factor to ensure their design optimization and operational safety. However, the existing analysis methods independently calculate the upper wind turbine structure and the lower pile foundation with separate iterations, resulting in unclear deformation mechanisms, non-optimized design results, and unknown health status. This is a recognized “bottleneck problem” in the offshore wind power industry. Therefore, it is urgent to establish an “integrated” safety analysis method and intelligent diagnosis system.

Evolution Characteristics of Tamping Settlement Rate and Intelligent Prediction of Blast Waves for Underwater Blast Compaction of Rockfill Bed

Abstract

Underwater blast compaction technology for foundation beds features a remarkable compaction effect, adaptability to complex geological conditions, and controllable disturbance to the surrounding environment. It has been widely used in foundation bed treatment of marine engineering, such as port and wharf structures, cross-sea bridges, and offshore platforms, serving as a key process to ensure the safety and stability of superstructures. This technology uses instantaneous impact energy released by explosive detonation to induce intense vibration and displacement of bed particles, promoting particle rearrangement and pore filling, thereby improving the compaction degree and bearing capacity of the foundation bed. However, in the complex process of simultaneous underwater detonation of large charges impacting the rockfill bed, key issues, including the mechanism of blast shock wave action and compaction effects under different parameter combinations, still lack systematic and in-depth analysis in existing research. In view of this situation, experimental studies on underwater blast compaction characteristics of foundation beds are carried out combined with model tests. The research focuses on the internal compaction mechanism during blasting, the influences of different blasting parameters on the tamping settlement rate of rockfill beds, and the internal relationship among blasting parameters, foundation tamping settlement rate and bed pressure response is revealed. The influence weights of different blasting parameters (charge weight, spacing) on compaction effect are clarified. Meanwhile, intelligent reconstruction of blasting loads is conducted, providing an accurate propagation path of blast waves for the research. The results can provide a scientific basis for parameter design and quality evaluation of underwater blast compaction engineering.

Key Technologies for Floating, Transportation and Sinking of Large Immersed Tunnel Elements in Complex Environments

Abstract

The construction of immersed tube tunnels is of far-reaching strategic significance for the utilization of underwater space and the development of modern transportation systems. During the offshore floating, transportation and sinking of large immersed tubes, they are highly susceptible to complex marine conditions characterized by variable wave-current dynamic conditions and restricted navigational terrain, which directly threaten the stability of their attitude and the safety of maneuvering. With the continuous advancement of the “National Transportation Powerhouse” strategy, immersed tube tunnels have been rapidly developed in the Bohai Rim region, the Yangtze River Delta, and the Guangdong-Hong Kong-Macao Greater Bay Area. A systematic study is conducted on the integrated key technologies for the floating transportation, mooring and sinking of large tunnel elements. The research improves the coupled dynamic response mechanism of the immersed tube–installation barge system, establishes an accurate calculation model for the floating transportation and sinking characteristics of immersed tubes, and clarifies the influence mechanism of complex boundary conditions on the attitude of tunnel elements.

Title

Waterproofing and Sealing Solutions for Immersed Tube Tunnels

Abstract

As a core component of major river-crossing and sea-crossing transportation infrastructure, the sealing and waterproofing performance of immersed tube tunnels directly determines the service life, operational safety and durability of the project. It serves as a critical safeguard against high hydrostatic pressure, tidal disturbances, geological settlement and marine environmental erosion. Based on the full-life-cycle protection requirements of immersed tube tunnels, this solution integrates the whole-chain technologies, including material development, structural design, construction adaptability and operation-maintenance support, providing customized, high-performance and long-lasting systematic solutions. It has been successfully applied in a number of national key projects, such as the Hong Kong-Zhuhai-Macao Bridge Tunnel-Island Project, Shenzhen-Zhongshan Link and Dalian Bay Submarine Tunnel, helping the projects achieve the waterproofing target for a 120-year design service life.

The solution is developed around three core principles: layered protection, precise adaptation and long-term durability. Its core technical system covers two aspects: First, waterproofing of the tube segment body. By optimizing concrete mix proportions, improving impermeability grades, combined with special external waterproof coatings and construction joint water-stopping structures, the self-waterproofing capacity of tube segments is enhanced, thus controlling the risk of crack water seepage at the source. Second, joint sealing and waterproofing. A dual-seal system consisting of a GINA waterstop (primary seal) and an OMEGA waterstop (secondary seal) is adopted, together with customized rubber seals adaptable to structural displacement. Combined with the hydraulic compaction process, it achieves complete watertightness at tube segment joints, while ensuring the safety and durability of seals to effectively resist structural deformation caused by earthquakes, settlement and temperature variations.
