The Method of Determining the Preferred Structural Plane of Rock Slope in Open-Pit Mine Based on Kinematics Analysis and Its Engineering Application
The confirmation of the preferred structural plane of the slope is a crucial prerequisite for conducting stability analysis on mine rock slopes.Considering the difference in the influence of the spatial relationship between the occurrence of different rock mass structural planes and the slope occurrence on the slope stability,a method for confirming the preferred structural plane based on kinematics analysis was proposed.Firstly,the occurrence data of structural plane were projected onto the pole isodensity map by stereographic projection.Furthermore,the kinematics analysis method was introduced to analyze and screen out the occurrence data that affect the slope stability under different slope failure modes.Finally,cluster analysis was carried out on the screened occurrence data,and the preferred structural plane of the slope was obtained.The method was applied to an example of rock slope collapse in an iron mine.The results show that the grouping results of preferred structural plane obtained by the method for confirming the preferred structural plane of rock slope in open-pit mine based on kinematics analysis are reasonable and reliable,with high accuracy,which verifies that the method has good engineering application value.
