STATIC AND DYNAMIC ANALYSIS OF SATURATED AND UNSATURATED SOILS

建筑物、高速公路、隧道、水坝、斜坡和海上石油平台等工程结构都建造在土壤上或土壤中。因此，在土木工程设计中，预测这些材料在静态和动态载荷下的响应的能力是非常重要的，但是由于它们通常是非饱和的，具有非线性、非均匀和各向异性的特性，因此变得复杂。该项目旨在制定和实施新的计算工具，用于预测非饱和土壤的负荷-变形特性，还将涉及实验工作和现场数据模拟。长远目标是发展可供执业工程师使用的先进方法，从而改善工程设计和降低建筑成本。

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.
