Then,based on elastic-perfectly plastic constitutive model and Ducker-Prager yield criterion,the displacement and stability factors of the earth dam with or without seepage is analyzed by using of FEM and strength reduction principle,and the Influence of seepage to stability of.
然后采用理想弹塑性模型和D-P准则,运用有限元法和强度折减原理,分析了土坝在考虑渗流和不考虑渗流情况下的位移及稳定性系数,并通过对比分析了渗流对土坝稳定性的影响。
