摘　　要：将颗粒流方法与强度折减法结合,对匀质土坡稳定性进行了分析。通过对颗粒间的接触强度和摩擦系数同时进行折减,直到土坡破坏,此时的折减系数即为土坡安全系数。另外,由土坡颗粒的位移矢量图确定了滑裂面的位置。Combined with particle flow method and strength reduction method, the stability of homogenous soil slope is analyzed. Through reduction of contact strength and friction coefficient among particles until failure of soil slope, the reduction factor at this time is the safety factor of soil slope. In addition, the position of cracking surface is determined by displacement vector of slope particles.
