Sensitivity of stability parameters for soil slopes: An analysis based on the shear strength reduction method

The stability of soil slope is analyzed through explicit Lagrangian finite-difference method based on the strength reduction method. The predominance of this method is discussed. It is a fast method. Dilatation angle, cohesion and internal friction angle are taken into consideration in analyzing of soil slope. It is concluded that the safety factor will become bigger as the dilatation angle, the cohesion and the internal friction angle, while the plastic area and the slip plane will have fluctuation. The results can be used in practical slope design.
