摘要
溢流坝工作闸门是水工建筑物的重要组成部分。笔者对广西龙兴水电站溢流坝1号工作闸门进行了三维有限元仿真分析,分别计算在自重+设计水头、自重+动水水压两种工况下的闸门变形和应力分布情况,并将计算结果与现场检测结果进行对比,结果显示两者基本相同。该方法及理论可应用于类似闸门的有限元分析与检测。
The operating gate of overflow dam is an important part of hydraulic structures. Three-dimensional finite element simulation analysis of No.1 operating gate of overflow dam of Longxing Hydropower Station in Guangxi is carried out. The deformation and stress distribution of the gate are calculated respectively under two different conditions of the dead weight + design head and dead weight + hydrodynamic pressure. The calculation results are compared with the field test results, and the results show that they are basically the same. This method and theory can be applied to the finite element analysis and detection of similar gates.
