Experimental and numerical studies on internal erosion of granular soils

这项研究旨在提高我们对土壤内部侵蚀所涉及的机制的理解，这些机制可以在大型基础设施中引发不稳定和破坏。具体地说，将阐明颗粒和组织尺度上的形貌特征以及外加应力对内侵蚀的起始和演化的影响，以预测灾难性破坏发生的地点和时间。拟议的提案不仅将使广泛的科学和工程界受益，而且通过重新表述澳大利亚关于土木工程结构的建设、监督和退役的标准或指南，还将直接解决澳大利亚第二个最紧迫的问题--土壤和水。

This research aims to improve our understanding of the mechanisms involved in internal erosion in soil that can trigger instabilities and damage in large scale infrastructures. Specifically, influences of morphology features, at both grain and structure scales, and applied stress on the initiation and evolution of internal erosion will be clarified, to predict where and when the catastrophic failure happens. The proposed proposal will not only surely benefit a broad range of science and engineering communities, but also directly address the second most urgent problems, 'soil and water', in Australia, by rephrasing the Australia standards or guidelines for construction, surveillance, and decommissioning of civil engineering structures.
