Finite Element Analysis of Foundation on Inhomogeneous Rock Mass

Abstract

The finite element procedure that can allow for the nonlinear behavior of inhomogeneous rock masses and nonlinear interaction effects was described. The use of the interface and joint elements was presented. Inclusion of these elements very often change the results of the deformation behavior and the stability of foundations on rock masses. As for the typical examples, practical problems were solved and the influence of discontinuities in the rock mass was investigated. It is found that the results are significantly influenced by material properties, which should carefully be determined from the in-situ and laboratory tests.
