| 摘 要： | 对广东省北江飞来峡水电站厂房坝段在正常蓄水位、设计洪水位、校核洪水位等3种工况下的应力变形状态作了弹性和弹塑性有限元分析计算，得出了大坝特征点的应力值和位移值。对弹性和塑性计算结果以及大坝的工作状态分别进行了分析，结果表明大坝应力满足安全要求，具有较大的安全裕度，为水电站运行管理和防洪调度决策提供了重要参考资料。

| Abstract: | The stresses and deformations of the dam specific positions are obtained through calculation of the stress and deformation for the power house dam reach at conditions of normal storage water level, design flood level and check flood level by using the methods of elastic and elastic plastic finite element analysis. Through analysis of the differences of calculations by elastic and elastic plastic methods, the results show that the stress of the dam reach can satisfy the safety requirement of the dam, so the research can provide an important reference for the hydropower station safe operation and flood control decisions. |
