摘要：In order to reasonably consider the effect of flexibility of the input
   peak ground motion along the sliding body on the critical sliding
   acceleration and cumulative sliding displacement,the combination of ant
   colony complex method with limit equilibrium methods is used to search
   the position of potential sliding body.Based on the principle of the
   rigid Newmark sliding model,the average yielding acceleration is
   considered asthe critical acceleration during the analysis of sliding
   displacement.Analytical expressions of the average yielding acceleration
   are presented based on several common limit equilibrium methods.It is
   shown that the computational efficiency and accuracy of the refined
   Newmark sliding method based on the average yielding acceleration have
   been improved significantly.
