Abstract

An incremental, nonlinear finite element procedure is developed, suitable for deformation, stress and stability analysis of embankment dams with waterproof elements other than earth. The procedure is applied for analysis of hypothetical rock-fill dams with asphaltic facing and an internal asphaltic core - vertical and inclined. Studies are carried out to understand the prototype behaviour of these types of rock-fill dams. Both rock-fill and asphalt behaviour is modelled by using hyperbolic relations. Due to inter- element compatibility, the conventional use of finite element method (FEM) makes impossible the consideration of the effect of differential displace- ments along the interface of different materials. In order to get a correct and complete analysis in the interfaces rock-fill - rigid foundation, asphalt
