| 摘 要： | 边坡稳定性评价是边坡施工期的关键问题之一，单一的评价方法具有不充分性和不完善性。锦屏一级水电站左岸边坡地质条件复杂，边坡稳定性问题突出。分析了左岸边坡岩体变形破坏机理和失稳模式，计算了各种失稳模式的安全稳定系数，结合多种监测成果以及参考几个典型人工岩石边坡失稳及监测结果，对锦屏一级水电站左岸岩石高边坡稳定性进行了综合评价。研究结果表明左岸边坡目前基本处于稳定状态，边坡支护设计基本满足边坡稳定性要求。并提出了边坡安全监测建议。

| Abstract: | The stability evaluation of high rock slope is one of key issues during construction period.A unitary evaluation method is inadequate and incomplete.The stability of left bank slope of Jinping First Stage Hydropower Station is very outstanding because of its complicated geological conditions.The deformation mechanism and slide modes of left bank slope were analyzed and the safety factor of each mode was calculated.The stability of left bank slope during construction period was evaluated synthetically by usi... |
