| Abstract_FL | Aiming at the problem of optimising the spatial morphology of the east side of Qidashan iron mine,based on the analysis of the engineering geological conditions of the slope,the limit equilibrium method and numerical simulation method are combined to evaluate the stability of the original design boundary slope.The shape parameters of the boundary slope are optimized and the influence of tracking distance on the three-dimensional stability of the slope is explored.The research results indicate that the boundary slope angle designed using the level by level optimization method is 46°,and the two-dimensional stability coefficient of the slope in each stage meets the requirements of safety reserve coefficient;the three-dimensional stability coefficient of the slope has a negative correlation exponential function relationship with the tracking distance.When the tracking distance is 50 m,the slope angle from the east side of Qidashan Iron Mine to the boundary can be designed as 48°,and the overall slope angle has been increased by 2°,which has significant economic benefits. |
