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.

该项目将缩小浅层基础在可变饱和土壤中的性能的知识差距。它将在不饱和土壤力学，弹性塑性理论，数值建模，极限分析和实验研究中整合专业知识。它将对使用最近开发的实验测试设施进行单调载荷的不饱和土壤上建立的基础进行严格的理解，并使用有限元元素，特征的方法和零扩展线理论进行分析。行业的影响和采用将直接通过世界第一设计工具，这些工具纳入了吸力对轴承能力，和解和安全性的影响。
