摘要
本文提出了压力钢管取消伸缩节后厂坝联结结构形式的优选准则，并通过对某大型水电站整体结构进行三维有限元分析，确定了最优模型和最佳明管长度，给出了初步设计阶段明管管壁厚度的计算公式．
An optimum criterion for the structures of junction between dam and power house without expansion joint had been proposed.The structural analysis of a large hydroelectric power station is accomplished by using 3-D finite element method,and an optimal model an optical length of exposed pipe are given with the simple optimization method.Finally,a method to calculate the thickness of exposed pipe is proposed.
