Application Of Joint Elements At Finite
Element Analysis Of Embankment Dams

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
