Research on Analyzing Earth Rockfill Dam Seepage and Slope Stability

Abstract:

Seepage damage has been one of the most important factors that affect the safe operation of embankment dams, So more consideration is taken into the saturated soil more than non-saturated soil. In this paper, we carry on the experiment by using SEEP/W software to take the flow field analysis of unsaturated soil of the core embankment dam. Based on the experiment, we analyzed the normal water level of dam seepage line, checked the flood level lower position, the pressure and the flow hydrodynamic calculations of the dam such as hydraulic slope, analyzed different water seepage under the dam changes, as well as the reason of the causing damage to the dam and the effect on the heart wall seepage is also analyzed. We found that the reason of dam destroyed is due to the hydraulic slope caused by excessive exports, we propose the corresponding seepage control measures. To solve this problem, we conducted the filtration for the seepage export processing.
