This project will close the knowledge gap of how shallow foundations perform in variably saturated soils. It will integrate expertise in unsaturated soil mechanics, theory of elasto-plasticity, numerical modelling, limit analysis and experimental investigation. It will achieve a rigorous understanding of footings founded on unsaturated soils subjected to monotonic loading using a recently developed experimental testing facility, and analyses using finite elements, the method of characteristics and zero extension line theory. Impact and adoption in industry will be direct through world first design tools which incorporate the influence of suction on bearing capacity, settlement and safety.

该项目将缩小浅基础在不同饱和土壤中的表现的知识差距。它将整合非饱和土力学、弹塑性理论、数值模拟、极限分析和实验研究方面的专业知识。它将使用最近开发的实验测试设备对建立在承受单调荷载的非饱和土壤上的基础进行严格的了解，并使用有限元、特性方法和零延伸线理论进行分析。通过世界上第一个设计工具，该工具将吸力对承载能力、沉降和安全性的影响纳入考虑，从而直接影响和采用。
