The reliability analysis of Municipal Solid Waste Slope based on strength reduction FEM

This paper has taken the character of unsaturated soil strength of garbage filling –burying body into consideration,and carries on the reliability analysis of the slope of garbage filling-burying body on the basis of the strength reduction FEM.Considering the physical mechanics indexes'variability of the garbage filling-burying body,this paper has calculated the overall reliability index of the garbage soil slope with FOSM.The result indicated that the variability of cohesion C and internal friction angle are in a greater impact on reliability.
