摘要
该文以某露天铁矿高陡边坡的危险性为研究对象,在现场踏勘实际材料和前人成果的基础上,采用Saaty层次分析法选取对岩石边坡影响敏感的5个致滑因素进行分级,借助ArcGIS提供的DEM提取算法建立相应的TIN模型,参照一定规模数量的边坡滑塌案例进行统计,赋予致滑因子栅格图像相应的关键属性,由栅格计算器对5个图层加权叠加,得出采场高陡边坡易滑性分区图,为以后矿山高陡边坡稳定性问题的研究提供参考依据。
This paper takes the risk of high steep slope in a open pit iron mine as the research object, based on the field investigation actual material and previous research ,by using Saaty hierarchy analytic process, 5 factors which are sensitive to the influence of rock slope slide are classified. The corresponding TIN model is established by means of DEM extraction algorithm provided by ArcGIS. Refrence to a cer- tain number of slope collapse case to statistics,the corresponding key attributes of the grid image of slip factor are given. 5 layers are weighted superposition by a raster calculator, the zoning map of easy slip high and steep slope of stope is obtained. It can provide reference basis for the study of the stability of high and steep mine slope in the future.
