Slope Stability Evaluation of Reinforcement Effect for Fengchan Earth Dam

Based on the typical section of the dam and geological survey data, the model for analyzing the stability of the typical section of the dam slope is established. In this paper, the calculation model is used to compute the stability of dam slope in the Fengchan reservoir before and after the reinforcement. The results show that the condition of dam slope stability is better. After the reinforcement, the seepage slope of each partition and seepage discharge decrease significantly and the stability safety factors of dam slope in various engineering conditions increase obviously, which can meet the requirements of specification.
