Abstract：In order to further research on the deformation failure mechanism and stability of slope along volcanic rock mines in the southeast region of Zhejiang Province,the article takes a slope on an island in Wenzhou City,Zhejiang Province as an example.Based on a comprehensive investigation of the structural characteristics and deformation-destruction characteristics of the slope rock mass,combined with the results of deformation monitoring,the article analyzes deformation-destruction mechanism of this type of slope,and carries out numerical simulation verification using 3DEC discrete element program.The results show that the deformation failure of rock slope is mainly controlled by its own structure and regional main discontinuities output state.The cracks intersecting with the large angle of the slope evolve into deformation side boundaries,while those intersecting with small angles or tending to outside of the slope or their combinations evolve into deformation bottom boundaries.The protruding parts of the slope are weak areas in terms of stability,so plane linear changes should be minimized in mine slope design to enhance overall stability.
