Laboratory and Theoretical Investigation of Soft Clay Behaviour under Cyclic Loading Stabilised by Prefabricated Vertical Drains

澳大利亚沿海地区正面临着人口快速增长带来的越来越大的压力，这需要对公路和铁路、港口和建筑等民用基础设施进行持续的资本投资。许多地区都有软的可压缩粘土，这给基础设施的设计和建设带来了挑战。使用预制垂直排水沟(PVD)加固土壤可以降低建筑和维护成本，增加土壤强度将提高基础设施的性能。在这个项目中，将彻底研究由PVDS稳定的循环荷载下的土壤特性。广泛的实验室测试将导致在软土上更有效的设计和施工，包括公路、铁路和机场跑道。

Coastal Australia is under increasing pressure from rapid population growth that requires continual capital investment in civil infrastructure such as road and rail links, ports and buildings. Many regions have soft compressible clays that present challenges for infrastructure design and construction. The use of prefabricated vertical drains (PVDs) in stabilising soil can reduce construction and maintenance costs, and increased soil strength will enhance the performance of infrastructure. In this project, the soil behaviour under cyclic loads stabilised by PVDs will be thoroughly investigated. Extensive laboratory testing will result in more efficient design and construction on soft soils, including roads, railways and airport runways.
