Analysis of subsidence due to a point sink in an anisotropic porous elastic half space

Abstract

Abstract Analytical solutions of the long‐term consolidation deformation and excess pore water pressure due to fluid withdrawal from a saturated anisotropic porous elastic half space are presented. In the analysis, both the permeability and the elastic properties are considered cross‐anisotropic. Cases of pervious and impervious half‐space boundary are studied. The consolidation settlements as effected by the anisotropy and boundary conditions for pore water are illustrated and discussed.
