Abstract
Based on limit analysis and pseudo-dynamic methods, a proposed method for evaluating slope stability under seismic conditions that considers dynamic changes in the axial force of the anchor cables is presented. The case study shows that compared to the computational conditions that neglect the dynamic changes in axial forces, the dynamic safety factors obtained by the proposed method are greater, whereas the dynamic variation amplitudes of the dynamic safety factors obtained by the proposed method are smaller. The better anti-seismic effect of the anchor cables due to considering the dynamic changes in axial forces is reflected by the proposed method.
