摘要:This paper divides the unstable slopes in Huachi County into soil and rock. The final deformation evolution of unstable slopes is landslide, collapse and continuous cumulative deformation to maintain an unstable state, in which landslides and collapse disasters may dominate. The typical Donggou unstable slope profile in the county is selected for analysis, The calculation results and numerical simulations shows that the slope is stable under the conditions of self-weight and earthquake; The sections of the slopes 1-1/ and 3-3/ are basically stable under heavy rainfall conditions. The calculation results are basically consistent with the qualitative analysis, indicating that heavy rainfall is the main cause of unstable slope deformation.
