In order to determine the sliding surface of a debris landslide more accurately and calculate its stability coefficient,through the collection,arrangement and analysis of related data,the site investigation and exploration of engineering geology,indoor and outdoor physical mechanics test,the sliding surface of the debris landslide is determined by the method of limit plastic strain analysis of large deformation elastic-plastic FEM.Furthermore,the sections of different utilization degrees of shear strength are determined on the basis of plastic strain value under the limiting state of the landslide.This paper proposes the unbalanced-thrust method which comprehensively thinks over the different utilization degrees of shear strength of rock and soil on the sliding plane.The analysis of a concrete engineering example shows that this method may be very well used to analyze the stability of a debris landslide and calculate its stability coefficients,which can more really reflect the actual locating state of a debris landslide.
