| 摘 要： | 滑坡是露天矿中一种常见和重大的灾害,是影响矿山安全生产的重要因素,因此对露天矿边坡稳定性评价有重要的现实意义.在建立露天矿三维地质模型的基础上,对地质模型进行切割产生任意位置剖面;根据边坡实时监测数据自动生成岩移监测曲线和滑坡预警线,根据曲线确定可能发生滑坡区域,在三维地质模型的相应位置切割剖面,作为边坡稳定性计算的依据;采用Bishop法和剩余推力法两种方法计算边坡稳定性系数,进而评价露天矿的边坡稳定性.

| Abstract: | Landslide is a common and important disaster in open-pit;it is the important factor of mine safety production,therefore,to evaluate the slope stability of open-pit is of important practical significance. On the basis of constructing 3D geological model of open-pit,the model is cut to produce random position profile. According to the real-time monitoring data of slope,rock movement monitoring curves and landslide warning-line can be produced automatically. According to the curves,the area where may take plac... |
