Slope instability is a dynamic evolution process involving large slope deformation, which often determines the consequences of landslide failure. In this paper, the stochastic limit equilibration-material point method is used to study the dynamic evolution process of different failure modes of slope under the condition that the slope parameters are not uniformly distributed in the space of a hospital environment. Based on this, in this article, the influencing factors of the study on slope deformation and failure mode according to deformation and destruction will be divided into sandstone slope deformation and destruction difference weathering, the unfavorable combination of bedding structure surface and cutting layer structure surface, artificial excavation disturbance, and the deformation characteristics of failure mode and all kinds of process will be analyzed. Finally, Phase2 software was used as a tool to study the stability and failure mode of the rock slope, and it was found that both side slope angle and rock strata dip angle would have an impact on the slope deformation and failure.
