STATIC AND DYNAMIC ANALYSIS OF SATURATED AND UNSATURATED SOILS

建筑物、公路、隧道、水坝、斜坡和海上石油平台等工程结构都是在土壤上或土壤中建造的。因此，预测这些材料在静、动荷载作用下的响应能力在土木工程设计中具有重要意义，但由于这些材料通常是非饱和的，具有非线性、不均匀和各向异性的特性，因此预测这些材料的响应能力很复杂。该项目旨在制定和实施新的计算工具来预测非饱和土壤的载荷变形行为，并将涉及实验工作和现场数据的模拟。长期目标是发展先进的方法，可以由执业工程师使用，从而导致改进工程设计和降低建设成本。

Engineering structures such as buildings, highways, tunnels, dams, slopes and offshore oil platforms are all constructed on or in soils. The ability to predict the response of these materials under static and dynamic loading is therefore of major importance in civil engineering design, but is complicated by the fact they are typically unsaturated with nonlinear, inhomogeneous, and anisotropic properties. This project aims to formulate and implement new computational tools for predicting the load-deformation behaviour of unsaturated soils, and will also involve experimental work and simulations of field data. The long term objective is to develop advanced methods that can be used by practising engineers, thereby leading to improved engineering design and reduced construction costs.
