摘要
Based on the Mohr-Coulomb Strength Criterion,a point safety factor as the ratio of the shear strength of the slip zone to the shear stress parallel to the gliding direction is defined.The safety factor of the landslide as the weighted average value of the zone point safety factor with its zone is defined.The sliding mechanism is studied quantitatively by means of analyzing the distribution of the zone point safety factor.Landslide stability can be evaluated through the safety factor.In the inversion analysis,the sliding mechanism and stability can be satisfied simultaneously.So the corresponding strength parameter is a reasonable inversion result.
