Abstract

Soil-water-air coupled analyses are performed in order to discuss the effects of seepage and overtopping on the deformation and stability of a river levee. The governing equations are derived based on porous media theory at finite strain. The weak forms of the momentum balance equations of the overall three-phase material and the mass and momentum balance equations of the pore fluids (water and air) at the current configuration are implemented in a finite element model. The effective stress - strain relation is assumed to be an extended modified Cam-Clay model in order to consider suction effects of unsaturated soil. The numerical results showed different distributions of deviatoric strain in the river levee between with and without overtopping on the river levee.
