通过对某大型水电站典型坝段厂房整体结构进行三维有限元计算分析 ,得出了在常规荷载作用下厂坝间压力钢管的变位及受力情况 ,可为有关取消厂坝间压力钢管伸缩节的论证提供依据 ,并提出了取消伸缩节后所应采取的结构措施。 Through the three-dimensional finite element analysis and calculation of the overall structure of the typical dam section of a large hydropower station, the displacement and stress conditions of the pressure pipe between the dam and the dam under normal load are obtained. Provide justification for the argument, and put forward the structural measures to be taken after the cancellation of the telescopic section.
