飞来峡水利枢纽排漂孔坝段应力变形计算分析

Stress and Deformation Analyses of a Dam with Floatage Drains of Feilaixia Hydropower Project

对飞来峡混凝土重力坝排漂孔坝段在完建、正常蓄水位、校核洪水位等三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,给出了大坝特征点的位移值和应力值,计算结果表明,大坝应力满足安全要求。

Using the elastic and elastoplastic finite element method,the stress and deformation analyses of the dam with floatage drains of the Feilaixia Hydropower Project under none water level,normal pool level and check flood level, have given a lot of displacements and stresses of special dots.The calculating results show that the stresses of the dam satisfied safety requirements.
