Slope Stability Analysis Based on Rock Mass Structural Plane Identification Technology
Structural plane is the most important factor affecting the stability of rock slope.The 3D model of an open-pit slope is obtained by using the UAV oblique photography technology,and the rock mass structure 3D recognition system(RMV3D)is combined to identify the rock mass structure plane quickly and accurately.Through statistical analysis of the structural plane of the slope,three groups of dominant structural planes are identified,among which J1 and J2 are the main ones.Based on the results of structural plane analysis,a two-dimensional structural plane network model of slope rock mass is established.Com-bined with finite element simulation,the influence of different structural plane combination modes on slope stability is discussed.The results show that the existence of structural plane leads to the increase of horizon-tal stress and displacement at the bottom of the slope,which has an adverse effect on the stability of the slope.The stress-strain characteristics of the slope are basically the same as those of the single bedding structural plane slope under the two combined modes.
