One of the most important factors for designing a safe foundation is amount bearing soil capacity and allowable settlement according to type structure. Therefore, in geotechnical engineering, aim improve foundations' many ways, some which are expensive, other section difficult implement sites. Skirted foundations consider as an ideal solution cost-wise tolerance by reducing materials installati...

A bounding surface plasticity model based on the effective stress concept is presented to describe behaviour of unsaturated structured soils subjected hydro-mechanical loadings. The structural degradation effects compressive and tensile strength are considered through controlling size surface, allowing for a smooth transition response from unstructured states. modelled using work hardening appr...
