Abstract:
The finite element strength reduction method was used to analyze the upstream and downstream dam slope stability of Jinfoshan asphalt concrete core wall rock-fill dam under different working conditions including the completion period, impoundment period, and sudden water-level decreasing period. The results showed that the dam slope safety coefficients meet the standard requirements under the completion, impoundment, and sudden water-level decreasing periods. Compared with the limit equilibrium analysis method, the finite element strength reduction method can overcome the disadvantages of limit equilibrium analysis method to determine the specific location of slide surface and the size of sliding mass in the analysis of slide surface and plastic area, but the results determined by the finite element strength reduction method were safer. Therefore, the combination of the two methods to analyze the slope stability can provide more reasonable results.
