摘要
在露天矿边坡稳定性分析时,可根据边坡内结构面和边坡形态的空间组合关系,利用赤平极射投影法对其稳定性进行初步分析,确定可能的滑塌模式及滑塌范围。通过对赤平极射投影法原理的介绍,以平面投影为例,分析对比了传统画法与CAD图解法的过程,表明CAD图解法作图效率更高。结合具体工程实例应用,证明了该方法在边坡稳定性分析中具有良好的实用性。
In the slope stability analysis of open pit, the initial slope stability can be analysed according to the spatial combination relations in the slope structural plane and slope shape by stereographic projection method, meanwhile the possible sliding mode and sliding range is determined. This paper introduces the stereographic projection method, and compares with the traditional drawing process and CAD graphic method in the case of plane projection. The results show that the CAD graphic method is more efficient. Combined with practical engineering application, it proves that this method has good practicality in slope stability analysis.
