【摘要】 运用ANSYS程序建立了李家峡水电站坝区三维有限元模型 ,计算分析了不同工况尤其是大吨位预应力锚索施加后大坝及坝肩岩体的位移和应力分布特征以及左坝肩的稳定性 ,对电站的安全运行有重要的参考价值更多还原

【Abstract】 A 3-D FE model around the arch dam area of Lijiaxia Hydropower Station has been established by use of the program of ANSYS.Distribution characteristics of displacement and stress as well as stability of the left abutment have been calculated under different conditions,especially after the high\|tonnage prestressed anchorage cables were applied.The research results are of high referential value to safe operation of the hydraulic power station.更多还原
