In jointed and fractured slope of surface coal mine, landslide probability increases significantly. Therefore, it is with great significance for surface mine to forecast and analysis the risk of fractured rock slope and the deformation law, so as to take effective prevention and control measures to assure safety and high effective product. This paper takes the jointed rock slope of north wall in Shengli East2#surface mine as research background, and sets up the joint distribution generalized model of slope rock mass, according to the field investigation and statistical analysis. The model is based on the Monte-Carlo principle to simulate the jointed rock slope with three dimensional network, and through the bottom friction similarity simulation experiment and discrete element numerical analysis to carry on systematic research on the deformation law of slope in the case of different distributions and occurrences of fractured rock mass, then the landslide model of fractured rock mass is determined. Furthermore, combined with qualitative analysis and quantitative analysis with AHP method, this paper establish a comprehensive evaluation model of joints and fissures slope deformation controlling management measures, and put forward the optimal project control scheme, then, analyzes the engineering application effect by case study. Finally, the results of this paper have important reference significance on stability research and analysis of the similar slope and landslide control. |
