Abstract: The engineering geological drilling exploration is carried out in the Mijiangou tailings dam area to serve the heightening design of enlarging its volume. According to the permeability parameters of the three zones, the tailing sand, the weathered rock mass and the rockfill of initial dam, determined by the inverse analysis based on the drilling exploration results and the heightening design plan, the seepage field in the heightened dam area is analyzed to get its distribution. The applied numerical method is the finite element one and the software is 3D-Seepage-Stress developed by the authors. It can be concluded that both the seepage free surface and the overflow point are very high under the heightening design plan, which is not profitable for dam stability and management. Also, the measures of drain pipes in the design of enlarging the volume are proposed.

Key words: tailings dam, heightening design, seepage field, FEM
