Formation Mechanism and Stability Analysis of a Landslide in the Three Gorges Reservoir Area
Abstract:
the paper introduces the basic characteristics of the landslide, analyzes the formation mechanism of the landslide, I think that the thick and loose efflorescent colluvial deposit on landslide offer material source of the landslide; Steep hill provides effective free surface for the landslide ; Heavy rainfall and human engineering activities are the main factors for the stability of the landslide. According to rock physical mechanics test and stability calculation results under different working conditions, afford a stability evaluation for the landslide. The results show that the landslide may lose stability when cutting slope in the leading edge, loading in trailing edge and suffering heavy rainfall, we should take the necessary measures to prevent and control.
