摘　　要：采用三维有限差分程序FLAC3D计算分析了天花板水电站库区堆积体在正常蓄水位、降雨及库水位下降工况下的变形规律,并采用强度折减法分析了其稳定性,计算结果表明,各工况下的位移与变形同现场实际情况符合。The three-dimensional finite difference program FLAC3D is used to calculate and analyze the deformation law of the accumulations in the Tian-hua-ban hydropower station reservoir area under operating condition of normal storage level,rainfall and reservoir water level decline.The stability of the accumulations is analyzed by the strength reduction method.The calculation results show that,the displacement and deformation under each working condition are consistent with the actual situation on site.
