摘　　要：针对城市泵闸工程周围建筑物密集、施工时往往难以实现一次拦断河道围堰导流,而分期围堰导流采用土石围堰结构亦有诸多不利条件限制等情况,以上海市某大型泵闸工程为例,利用泵闸永久结构作为纵向导流围堰,实现了分期导流。采用三维空间有限元计算手段分析该方案的合理性,该分期导流方案可为类似工程提供有价值的参考。With regard to the situations of urban pumping stations, the surrounding dense structures, the difficuh realization of cofferdam diversion hy one-time fiver closure during the construction period as well as the unfavorable restriction conditions for the stage diversion hy cofferdams by use of the earth-rockfill cofferdam structure, a large pumping station in Shanghai was taken as a study case. The permanent structures of the pumping station were regarded as the longitudinal diversion cofferdam, and thus the stage diversion was realized. Three-dimensional finite element methods were employed to analyze the rationality of the proposed scheme. The resuhs show that the proposed diversion scheme may provide valuable reference for similar projects.
