Coastal Australia is under ever increasing pressure from rapid population growth which requires continual capital investment in civil infrastructure, such as road and rail links and large buildings. Many regions have soft compressible clays that present challenges for infrastructure design and construction. The use of vacuum preloading, together with vertical drains for soft soil stabilisation, can reduce construction and maintenance costs, while the increased soil strength will enhance the stability of infrastructure. This project will deliver design guidelines and specifications of enhanced vacuum consolidation application, as well as improving industrial competitiveness and export earnings through increased technology transfer.

澳大利亚沿海地区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以及大型建筑等民用基础设施进行持续的资本投资。许多地区都有软可压缩粘土，这给基础设施设计和施工带来了挑战。使用真空预压以及用于软土稳定的垂直排水沟可以降低施工和维护成本，同时增加的土壤强度将增强基础设施的稳定性。该项目将提供增强真空固结应用的设计指南和规范，并通过增加技术转让提高工业竞争力和出口收入。
