Abstract: The principle of the limit equilibrium method is discussed firstly; then the shortcoming of the residual thrust method is analyzed; and the improvement is conducted. The basic idea of the improvement is: when the yield occurs at a slice face, the Sarma method will be applied to calculate the action between slices, i.e., the shear force is calculated by the Mohr-Coulomb criterion while the horizontal thrust is unchanged. Finally, the verification of the improved residual thrust method is shown; and the engineering application to Sanbanxi Hydropower Project is illustrated.

Key words: landslide stability analysis, limit equilibrium method, improved residual thrust method
