Static deformation of a multilayered half-space by internal sources

Abstract

The method of layer matrices is applied to solve the problem of the static deformation of a multilayered elastic half-space by buried sources. Each layer of the multilayered medium is assumed to be homogeneous and isotropic, and the interfaces are assumed to be in welded contact. The point source ia represented as a discontinuity in the z-dependent coefficients of the displacement and stress integrands at the source level. Source functions are obtained for the six elementary displacement dislocations. Explicit expressions for the surface displacements are calculated for a vertical strike-slip and a vertical dip-slip fault.
