This paper presents a slope stability analysis method combined with the limit equilibrium and finite element simulation. Based on the simulated stress of a slope, the safety factory of one element can computed with Mohr-Coulomb criterion, and introduces the Dijkstra algorithm of graph theory to search the dangerous slide surface combined with limit equilibrium method. For an examine slope, the simulated results of safety factor and location of dangerous sliding surface is close to the strength reduction method. Sensitivity analysis results show that, the safety factor of slope is decreased with the increasing height and inclination of slope, but decreased with the decreasing cohesion and friction angle.
