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.

建筑物、高速公路、隧道、水坝、边坡和海上石油平台等工程结构都建在土壤上或土壤中。因此，预测这些材料在静态和动态载荷下的响应的能力在土木工程设计中非常重要，但由于它们通常具有非线性、不均匀和各向异性的不饱和特性，因此变得复杂。该项目旨在制定和实施新的计算工具来预测非饱和土的荷载变形行为，并且还将涉及现场数据的实验工作和模拟。长期目标是开发可供执业工程师使用的先进方法，从而改进工程设计并降低施工成本。
