Modeling of unsaturated soil considering the effect of saturation directly

Abstract:

In this paper, a new constitutive model, using skeleton stress and degree of saturation as independent state variables, is proposed for unsaturated soil, in which the influence of the degree of saturation can be properly described. In the model, a very simple moisture characteristics curve considering moisture hysteresis of unsaturated soil is also proposed The moisture characteristics curve can not only be applied to secondary drying process but also primary drying process originated from sl...
