This paper presents a modified constitutive model to predict post-construction movements of compacted fills due to wetting based on the results of anisotropically-consolidated undrained (ACU) triaxial compression tests. The constitutive model is coded in the FISH language of the finite difference numerical software FLAC. The model allows deformation along the major and minor principal stress directions instead of the vertical and radial directions and user-defined wetting fronts to predict movement with time. The lateral and vertical progressive surface movement induced by top-down wetting is simulated and the results illustrate how the differential vertical and lateral movement at the ground surface can change during the course of top-down wetting.
