The aims of the project are to provide new data on the conditions under which liquefaction failures can occur in soil materials that are intermediate between sand and clay, and to develop models to describe this behaviour. This project addresses two significant problems: liquefaction failures which occur in silty sediments on continental slopes and produce tsunamis, and liquefaction in unsaturated ship cargos with intermediate gradings which lead to ship losses. The outcomes of the project are expected to be greater understanding of the factors controlling liquefaction in silty materials, a better understanding of the risk of submarine landslides, and models which can be used to predict the conditions under which liquefaction can occur in ship cargos.

该项目的目的是提供关于介于砂和粘土之间的土壤材料可能发生液化破坏的条件的新数据，并开发描述这种行为的模型。该项目解决了两个重要问题：大陆斜坡上粉质沉积物中发生的液化失效并产生海啸，以及中间等级的不饱和船舶货物中的液化导致船舶损失。预计该项目的成果将是更好地了解粉质材料液化的控制因素，更好地了解海底滑坡的风险，以及可用于预测船舶货物液化可能发生的条件的模型。
