| Numerical analog analysis technique has been widely applied to geo-technical engineering. This paper has exactly discussed how to solve the problem of slope stability and being an experience for the later analysis of slope stability .In consideration of the geological conditions of WangXuan slope of Lao Chang Tin Mine in Yun Xi Company, Based on limit balance method , three dimensional finite element method(3D) and discrete element method, computer analogue and calculations analysis are carried out to WangXuan slope. The three methods all have merits and defects, they each can be supplementary to the other through associate application, the outcomes and the practical conditions matched well. At the same time by utilizing the limit balance we calculate and analyze the sensibility of Wang Xuan slope. Through the analysis of calculating results, we get the main factors of affecting the slope stability of Wang Xuan slope, and then the results provide the evidence for slope disposal. In this way, the stability analysis of slope is made systematically and completely and provid the way of reinforcing disposal, which has provided reliable basis of theory proof for mine. |
