3-Dimensional Boundary Element Analysis of Seepage Force in Anisotropic Rock Mass of Dam Foundation

3-D boundary element analysis of groundwater flow and seepage force in anisotropic Permeability rock mass are discussed. Results of calculation show that the anisotropy of rock mass have a definite effect on the distribution and magnitude of the seepage force in rock mass of dam foundation; and the drainage measurement has significant effect in improving the uplift under dam.
