Analysis of embankment failure mechanism in reservoirs due to rainfall infiltration during heavy rainfall

Many heavy rain disasters have occurred in recent years Japan. The maintenance of water storage facilities such as dams has become a global issue. aim is to simulate the failure mechanism reservoirs which slip on downstream slope embankment due rainfall August 2019 This study proposes simulation method for evaluating stability with respect fluctuations level and infiltration from surface using two-dimensional saturated–unsaturated seepage flow based finite element method. Moreover, safety factors during were calculated simulated line. By considering infiltration, factor decreased significantly, occurrence in-situ position could be reproduced. In conclusion, must considered when reservoir body rainfall.
