    Abstract
  • The west slope of Tianwan nuclear power station is a slope related to nuclear safety. When evaluating the stability of the slope, the seismic action should be determined according to the ultimate safe ground motion (once in ten thousand years) of the nuclear power station, and the slope stability coefficient should meet the requirements of the code for seismic design of nuclear power station. Based on the depth study of the engineering geological conditions of the west slope of the nuclear power station, considering various calculation conditions, the stability of the slope is comprehensively evaluated by using the limit equilibrium method and the finite difference method. The results show that the original west slope of Tianwan nuclear power station is stable as a whole, but it still has the risk of local sliding under rare seismic. The west slope of Tianwan nuclear power station formed after excavation process after is stable in both natural and rare seismic conditions, and it will not bring the threat to buildings which related to nuclear safety.
