| 摘 要： | 某水电站导流洞进口控制段过水断面较大，封堵门设计水头达到75．52m，以结构力学方法计算，难以反映结构实际受力情况且配筋量较大．为反映结构应力应变实际情况，利用ANSYS有限元分析软件，建立某水电站导流洞控制段三维模型进行有限元计算，重点分析闸门颈口，边墩，中墩，顶板和底板等部位应力应变情况，为结构设计及结构配筋优化提供依据，也为今后的实际工程提供了有意义的参考．

| Abstract: | Since the control section of diversion tunnel of a hydropower station has large intake cross-section and the design water head is 75.52m; it is difficult to reflect the actual stress and strain by using the method of structural mechanics. Based on setting up 3D model and using analysis software, the stresses and strains of gate neck, side pier, mid pier, roof, floor and any other parts, are analyzed emphatically. The results offer a theoretical foundation for the design of a hydropower station, a helpful reference for actual projects in the future. |
