Abstract

Abstract

This paper selects Boredao scenic spot in Shenxianju scenic area as the research object, use the uav aerial photography technology to complex terrain modeling. On the basis of the characteristics of topographic features, engineering geological conditions and the destruction of slope rock mass, combine with Flac3D finite difference numerical simulation technology and 3DEC discrete element numerical simulation technology, the whole stability, stress distribution and displacement distribution of rock mass are simulated by Flac3D; the process of deformation and collapse of the same model and the local stability of rock mass is simulated by using 3DEC discrete element numerical simulation. Combined with the results of simulation analysis, the stability of rock mass is evaluated comprehensively to increase the reliability of numerical simulation analysis. The results of numerical simulation show that the stability of rock mass is very low, and the results are basically consistent with the actual survey results. Therefore, it is suggested to avoid the road.
