摘　　要：通过地质勘查,查明了上新田滑坡体工程地质条件,在此基础上,结合滑坡体的变形特点对其进行了二维稳定性计算,分析评价了滑坡体的稳定性。结果表明,滑坡体整体现状(即天然工况)稳定,在暴雨工况下,整体仍为稳定,但在地震工况下,稳定性急剧下降,稳定系数为1.07,整体为基本稳定。The potential Shangxintian landslide has a serious adverse effect on the construction and the future operation of the Wudongde Hydropower Plant and its dam.It is therefore necessary to conduct an extensive safety evaluation on its stability.The two dimensional stability analyses are performed based on the geotechnical investigation data.The results indicate that,under the normal conditions,the target slope is stable; under the storm rain condition,it is marginally stable.But,the stability under the seismic conditions is dramatically reduced with a factor of safety of 1.07.
