摘要
溢流坝泄洪闸结构设计对保证泄水建筑物乃至大坝的安全运行具有十分重要的意义和作用。以某水库除险加固工程为例,利用有限元数值模拟的方法对溢流坝泄洪闸中墩锚固竖井体型尺寸展开优化研究。结果显示,优化方案下锚固竖井重点部位的最大应力值明显降低,受拉区域面积也有所减小,可以为闸墩锚固竖井设计施工提供参考。
The structure design of spillway gate of overflow dam is of great significance and function to ensure the safe operation of discharge structures and even dams.Taking a reservoir reinforcement project as an example,this paper uses the finite element numerical simulation method to optimize the shape and size of the anchor shaft of the middle pier of the spillway dam.The results show that the maximum stress value of the key parts of the anchor shaft under the optimization scheme is significantly reduced,and the area of the tension area is also reduced,which can provide reference for the design and construction of the pier anchorage shaft.
