Aiming at the two-dimensional arbitrary shape for sliding slope

any element in the sliding body is selected as the object of study.The shear stress on the slip surface was calculated by static equilibrium relationship in the direction perpendicular to the external force.The method of vector sum method to define the safety factor is referenced and the direction of the sliding body downward trend is solved according to the distribution of the shear stress.The safety factor of the slope is obtained in this direction.By verifying with the classic example

the results show that the slope safety factor obtained by this method is basically consistent with that calculated by other methods.This method is proved to be feasible and can be applied to slope stability analysis

and the shearing stress of sliding surface has influence on the slope safety factor.
