| Abstract: | 3-D finite element analysis of groundwater flow and uplift in the dam foundation is discussed considering the anisotropic permeability of the rock mass.The calculated results show that the anisotropy of rock mass has a definite effect on the distribution and magnitude of the uplift in the dam foundation,and the measures of drainage has significant effect in reducing the uplift under the dam. |
