摘要
通过对比3个模型在高速水流脉动压力作用下的随机响应,分析出坝身孔口建筑物对坝体整体动力特性的影响性以及在孔口顶部设连接段作为深梁式弧门支承结构对闸墩所起的动力稳定作用。成果可为类似孔口结构设计提供参考。
Three model＇s vibration response to the high speed flow pulsating pressure has been compared in this paper. From this paper, we can see that overflow orifice structure has dynamical characteristic influence to the whole dam and the dynamical stabilization function of the connection structure on orifice. It can provide reference for other overflow orifice structure design.
