Conceptual reconstruction and optimization of the lightweight modular causeway system

浮动堤道系统作为快速将人和物资运送上岸的一种跨水域交通方式历来受到世界各国的广泛关注和研究。文章介绍了第二次世界大战以来浮动堤道系统的研发进程,分析了不同类型堤道系统的制作材料、相关部件间的连接方式以及适用的海况条件,梳理出了当前堤道系统存在的局限性。重点介绍了一种由铝合金模块组成的可快速部署的轻型堤块系统。该系统上部结构由兼容性较强的柔性连接件连接并由气动浮筒支撑,在满足挠曲极限的同时利用浮筒浮力实现了上部结构灵活性。最后,采用多目标结构优化模拟退火算法对该系统模块之间的柔性连接进行了研究,提出了进一步开展轻型堤块系统优化研究需要考虑的细节。

The floating causeway system has always been widely concerned and studied by various countries in the world as a cross-water transportation method for quickly transporting people and materials to shore.In this paper,the development process of the floating causeway system was introduced.The manufacturing materials,the connection methods between related components and the applicable sea conditions were analyzed,and the limitations of different types of causeway systems since the Second World War were outlined.This paper focused on a lightweight modular causeway system consisting of aluminum alloy modules that can be quickly deployed.The upper structure of the system is connected by flexible connectors with strong compatibility and supported by pneumatic pontoons and the flexibility of the upper structure is realized by the pontoon buoyancy while meeting the deflection limit.Finally,the multi-objective structural optimization simulated annealing algorithm was used to study the flexible connection between the modules of the system,and the details that need to be considered for further research on the optimization of the lightweight modular causeway system were proposed.
