Influence of rainfall intensity on infiltration and deformation of unsaturated soil slopes

In order to improve the understanding of the influence of rainfall intensity on infiltration and deformation behavior of unsaturated soil slopes, numerical 2D analyses are carried out by a three-phase elasto-viscoplastic seepage-deformation coupled method.From the numerical results, it is shown that...
