黄河上游某电站近坝滑坡稳定性研究

    STABILITY RESEARCH OF THE LANDSLIDE LOCATED IN RESERVOIR HEAD OF A POWER STATION ON THE UPREACH OF YELLOW RIVER

    • 摘要: 黄河上游某电站库首滑坡距大坝仅400多米,一旦失稳将会对大坝造成严重危害。笔者采用工程地质分析法及有限元数值模拟研究了滑坡的成因机制及应力场特征,在此基础上采用极限平衡法演算了滑坡在各种工况下的稳定状况。表明滑坡在蓄水过程中有可能产生下滑失稳。

       

      Abstract: The landslide located in reservoir head is about 400 m away from front of the dam. Its stability will influence the dam's normal operation directly. Based on the engineering geological characteristic and FEM numerical simulation, The paper analyze the formation mechanism and the stress field character of the landslide,and evaluate the landslide's stability in various conditions。The result indicates that the landslide may be in thestate of the activity while impound.
