Liquefaction of silty soils: Micromechanics, modelling and prediction

该项目旨在开发一种数值方法来了解粉质土壤中的液化。海底滑坡中粉质土壤的液化、尾矿坝坍塌以及运载铁/镍矿石的船只上的货物液化都可能造成财产损失，甚至是致命的。该项目将跨越尺度上的行为，并提供具有颗粒尺度机制的本构模型，以便更好地预测大尺度上的液化引起的破坏。所期望的结果是不同粉土含量的粉土的液化判据和预测液化土液化开始和流动的数值工具。

The project aims to develop a numerical approach to understand liquefaction in silty soils. Liquefaction of silty soils in submarine landslides, mine tailings dam failures and cargo liquefaction in vessels carrying iron/nickel ores can cause property loss and be fatal. This project will bridge the behaviours across the scales and deliver constitutive models that possess grain scale mechanisms for better prediction of liquefaction induced failure at the large scales. The expected outcomes are liquefaction criteria for silty soils with different silt contents and numerical tools to predict the onset of liquefaction and flow of liquefied soils.
