摘要
应用三维有限元计算伊泰兹水电站厂房上游墙止推环结构及其附近混凝土应力,并依据止推环及其邻近压力钢管在蜗壳不平衡水推力作用下的结构应力进行安全性评价。环后混凝土结构应力分布对结构配筋计算具有一定的参考价值。
By application of 3D finite element method,stresses of the thrust collar at powerhouse upstream wall and its surrounding concrete are calculated. Furthermore,their safety is assessed in accordance with structural stresses of the thrust collar and its neighboring penstock under the action of the unbalanced hydraulic thrust of the spiral case. The structural stress distribution of the concrete behind the thrust collar is referred to the reinforcement arrangement of the structure.
