摘要：
A significant anisotropy is found in the permeability coefficient of the rockfill of a concrete-faced rockfill darn. A two-dimensional and three-dimensional fixed-mesh FEM seepage analysis is conducted on the Jishixia concrete-faced rockfill dam under both normal and abnormal conditions where a crack occurs in the slab. The FEM meshes were obtained according to the designed schemes and topography of the dam. The seepage field and seepage amount of the dam were calculated. The effect of the crack's location on the seepage is also discussed. The calculation results show that the dam is stable in the seepage aspect under the normal design water level. The position of the crack has a significant effect on the seepage field and seepage amount of the dam.
