在澳大利亚沿海,丰富的软粘土经常阻碍包括路堤在内的交通基础设施的设计和建设。使用真空压力和预制垂直排水管(PVD)确保粘土的快速排水和固结,从而提高其抗剪强度和承载能力,同时减少长期变形。该项目的主要目的是通过最大限度地减少时间来实现所需的固结程度,从而控制施工后沉降和横向移动,从而实现可持续和具有成本效益的pvd真空系统的技术进步。在数值模拟的支持下,广泛的实验室和实地研究旨在产生新的行业指南和标准。
英文摘要
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.
