Earthquake is one important factors which affect the stability of red mud yard.According to the current codes and the finite element strength reduction method,the static stability of Longtayagou red mud yard is analyzed.The position and shape of slip surface,and the safety factor is determined.Based on the safety factor of pseudo static method with different seismic intensity,the displacement,acceleration and dy-namic safety factor of the red mud yard under two measured seismic waves are analyzed.The calculation results meet the specification requirements,and it can be determined to be stable.By comparing with the evaluation requirements of different methods and different specifications,the calculation results of the finite element strength reduction method can be judged as the evaluation criterion of stability analysis.
