Along Australia's coast, the abundance of soft clay often hampers the design and construction of transport infrastructure including embankments. The use of vacuum pressure and prefabricated vertical drains (PVD) ensures rapid drainage and consolidation of the clay, thus increasing its shear strength and bearing capacity while reducing long term deformation. The main aim of this project is to achieve technological advancement in sustainable and cost effective PVD-vacuum systems by minimising the time to achieve the desired degree of consolidation, thereby controlling post construction settlement and lateral movement. Extensive laboratory and field studies supported by numerical modelling aim to result in new industry guides and standards.

沿着澳大利亚的海岸，丰富的软粘土通常会阻碍包括路堤在内的运输基础设施的设计和建设。真空压力和预制的垂直排水管（PVD）的使用确保了粘土的快速排水和固结，从而提高了其剪切强度和轴承能力，同时降低了长期变形。该项目的主要目的是通过最大程度地减少实现所需合并程度的时间来实现可持续和具有成本效益的PVD-VACUUM系统的技术进步，从而控制后建筑和侧向运动。数值建模支持的广泛的实验室和现场研究旨在导致新的行业指南和标准。
