摘　　要：在给排水构筑物结构设计中,基础计算模型常常存在争论。一般情况,针对较小的水池底板,受力控制工况通常为空池静反力工况,也就是放空检修时水池底板所受的静反力,而对于较大的水池底板,如果采用静反力计算模型进行计算,将会在水池底板跨中产生非常大的弯矩,造成设计的不经济性。对于这种情况,工程设计中常常会考虑用弹性地基板模型来模拟底板受力情况,然而弹性地基板计算时的参数选取对受力的结果影响也很大。本文通过对给排水工程中的大底板水池进行了分析,并提出一些经验设计方法,可为类似工程作借鉴。During the structure design of water supply and sewerage engineering, there is a argument for the foundation calculation model. Normally, the controlling load case is the static reaction force while the tank is empty, which means the tank may take the maximum foundation force during the maintenance. While for larger tanks, if the foundation force is still calculated with the static reaction force model, the middle of the raft will take tremendous moments, which is not economical. Elastic foundation plate model is usually used to solve this case, however, the parameters of this model affect the results a lot. Water and sewerage tanks with large rafts were analyzed in this paper, and empirical design method was concluded, which may provide reference for similar engineering.
