Abstract
Based on the importance of soft rock slope stability in the production process of open-pit mines,combined with the geological conditions of the north slope in Pioneer Open-pit Coal Mine,the article adopts the research method of combining the numerical simulation of fluid-solid coupling and theoretical research to analyze the displacement field and stress field of the slope,and studies the damage mode and development trend of the soft rock slope under the self-gravitational stress of the high groundwater table.The results show that the surface mudstone of the north slope has undergone a wide range of horizontal deformation,and the maximum deformation is concentrated at the foot of the slope and in the middle of the slope.The vertical deformation of the slope is mainly manifested as the extrusion of the foot of the slope and the settlement of the top of the slope.According to the deformation of the slope,the article proposes two different preventive and control measures,namely,the clearing of the square to reduce the load and the anti-slip piles,and verifies the feasibility.关键词
