The Instability Mechanism of the Down TuDiLing Landslide

Abstract:

By making use of the developed strength reduction finite element codes based on which the matric suction can be considered, the sliding mechanism of the Down TuDiLing slope is analyzed. The results show that the stability of the Down TuDiLing slope is stable under the condition of employing the peak shear strength of soil and the lose of matric suction, but under the condition of the residual shear strength, the safety factor of the slope is decreasing to instability with the weakening of the matric suction, and a local sliding surface occurs. Through the strength reduction finite element computation, the position of the local sliding surface of slope can be differentiated and determined, so the problem of the local sliding should be paid to more attention in the reinforcement design.
