摘要： 矿山边坡的稳定性研究一直是岩土工程领域广泛关注的热点问题之一。结合广西田阳一处矿山工程边坡的实例，在分析其破坏模式的基础上，采用刚体极限平衡法、数值模拟方法和赤平投影方法综合评价了该边坡的稳定性，三种方法互为补充，为边坡防治提供了可靠的稳定性计算成果。提出的研究方法可为西南地区类似工程提供一定的借鉴和参考。

Abstract: Mine slope stability evaluation is one of the most current topics in geotechnical engineering. A mine slope in Tianyang County, Guangxi Province was selected as a case study in this paper. Based on the analysis of the failure mode of the slope, slope stability was evaluated using limit equilibrium, numerical modeling and stereographic projection approaches. Three methods from different prospective were used to evaluate the same problem to ensure reliability of the mine stability prediction. This case study can also provide an example for stability evaluations of similar mine slopes in Southwest China.
