Numerical Modeling of Water Flow in Expansive Soils with Simplified Description of Soil Deformation
2018
Archives of Hydro-engineering and Environmental Mechanics
In this paper we describe a numerical model of transient water flow in unsaturated expansive soils and the resulting soil volume change. The unsaturated flow equation is solved in a 2D domain using a finite-volume method and an explicit time discretization scheme. Strains in the soil mass are calculated by two simplified approaches, assuming that the strain state is either 1D (in the vertical direction only) or 2D with equal strains in horizontal and vertical directions. The model is applied to
