摘　　要：某水电站采用河床式开发,挡水建筑物为闸坝,闸墩高为60.5m,厚度仅为5m。泄洪闸闸墩顶部布置启闭机排架,启闭机高达26.5m。排架属于高耸结构,在遭遇地震时,启闭机排架将出现较大的地震响应,可能造成结构损害,从而影响工程安全。为研究方案是否可行,对泄洪闸闸墩、闸顶高排架进行三维有限元静、动力分析,以为类似结构设计提供参考。A certain hydropower station adopts riverbed development,with a water retaining structure of a gate dam,a gate pier height of 60.5 m,and a thickness of only 5 m.The top of the flood discharge gate pier is equipped with a hoist rack,with a height of up to 26.5 m.The rack belongs to a high-rise structure,and in the event of an earthquake,the rack will experience significant seismic response,which may cause structural damage and affect engineering safety.To investigate the feasibility of the proposed plan,a three-dimensional finite element static and dynamic analysis was conducted on the spillway gate pier and gate top height bracket,providing reference for similar structural designs.
