摘　　要：边坡在开挖过程中以及建成后长期运行中的安全稳定性对于水利水电工程建设的成败关系重大、影响深远。以南桠河姚河坝水电站厂房高边坡作为研究的工程实例,通过边坡安全监测资料的分析和岩体弹塑性参数的反分析,对边坡稳定进行了评价,得出该边坡处于稳定状态的结论。The safety and stability of slopes is very important for the successful construction and operation of a water conservancy and hydroelectric project. This paper takes the powerhouse slope of Yaoheba hydropower station in Nanya River as an engineering example. With the analysis on monitoring data and back analysis on rock elastic-plastic parameters, it concludes that the powerhouse slope is stable at present.
