Abstract

In order to study the stress and deformation characteristics of concrete cutoff wall in deep overburden foundation and the influence of seepage-stress coupling on the cutoff wall, combined with a practical project, using Abaqus finite element calculation software, the whole three-dimensional finite element model of the dam is built to calculate. The results show that the stress and deformation are concentrated in the top of the cutoff wall, and show the tendency of decreasing with the depth increased. By comparing the results of stress and deformation of concrete cutoff wall with consider or not consider seepage-stress coupling, founded that when consider the coupling effect, the displacement and the principal stress of cutoff wall varied at some degree. Therefore, ignoring the seepage-stress coupling can lead to the result of stress and deformation of the concrete cutoff wall is small.
