摘　　要：以南京市某大型全地下式取水泵房工程为例,对大跨度顶板、外壁板和底板进行了不同方式的计算分析。对于大跨度泵房顶板,采用单向密肋梁方案是合适的,同时应注意对端部采取加强措施。外壁板的计算应根据壁柱与壁板的实际刚度,考虑壁柱与壁板的协调受力。底板的计算应考虑桩基与底板的协调受力,可显著降低底板的内力。Taking a large-scale underground pumping house project in Nanjing as an example,the key structural components of this kind of pump house,including the large-span roof,outer wall plate and bottom plate,were calculated and analyzed in different ways.And the following conclusions and suggestions were drawn:For the large-span pumping house roof,it is appropriate to adopt the one-way multi-ribbed beam scheme,and at the same time,the strengthen measures should be adopted to the beam.The calculation of the outer wall plate should consider the coordination of pilaster and wall according to the actual rigidity of the pilaster and the wall.The calculation of the bottom plate should consider the coordination of the pile foundation and the bottom plate,which can significantly reduce the internal force of the bottom plate.
