摘　　要：随着工程规模的不断增大,雨水泵房的平面尺寸、埋深等也随之增大,给泵房的结构方案选型带来较大困难:大开挖方案造价较高,基坑与主体结构施工存在交叉;而沉井方案的下沉稳定性等方面又较难控制。本文主要结合工程实际,分析大型雨水泵房结构方案及配套措施的选择,可供后续类似工程参考借鉴。The size and the depth of the water pumping station has been increased, with the increasing of the project scale, which brings great difficulties to the structural scheme selection of the pumping station： The cost of the large excavation scheme is high, and the construction of the foundation pit and the main structure of the construction exist intersect, while the caisson sinking and stability are also difficult to control. In this paper, combined with the actual project, the selection of structural scheme and supporting measures of large water pumping station were analyzed, which can be used for reference for similar projects.
