Seepage Analysis of Concrete Face Rockfill Dam for Material Damage of Water Stop Structure
The safety operation of a concrete face rockfill dam (CFRD) built on covering layers depend on the integrity of its water stop system. So analyzing the dam seepage field before and after joint sealing damaged is significant, which includes the study of the influence on the dam seepage behavior when the water stop of peripheral joint and slab joint were damaged. In this paper, taken a specific hydropower station project as an example, the numerical analysis models of a CFRD for simulating the different water stop damage and failure types were established. Then the influence mechanism how the damage of the peripheral joint and slab joint affects the seepage gradient, saturated surface and seepage discharge inside the dam was analyzed, and the influence values were obtained. Therefore, the water stop area that needs to focus on is ascertained when the dam anti-seepage system was arranged.
