ABSTRACT
Compared with the traditional division method, the finite element strength reduction method takes into account the local plastic failure penetration area of the dam body in the analysis of the slope stability of the earth-rock dam, and comprehensively determines the instability of the dam slope. The calculation results are thus more practical. The calculation results of the single strength reduction coefficient method and the double strength reduction coefficient method are compared with the calculation results obtained using the Bishop method to verify the reliability and rationality of the calculation results of the finite element method as well as further improve the methods and means of the stability analysis of earth-rock dam slopes.
