摘　　要：利用流体力学的理论 ,推导出了支架式水塔附加地震作用的计算式 ,给出了晃动水的动力放大系数反应谱的部分计算统计结果 ,对《建筑抗震设计规范》(GBJ 11- 89)中支架式水塔水平地震作用的计算式提出了修改的建议 ,并给出了一个具体计算例 ,验证了在水塔的抗震计算中考虑附加地震作用的必要性。The formula of the additional earthquake actions of the water tower with supporters has been developed by the hydromechanics theory,and a part of statistical results relating to response spectra of magnified coefficient has been presented.The ideas proposed in this paper may probably be adopted for revision of the horizontal seismic calculation of a water tower in “Building Seismic Design Codes”(GBJ 11-89).The necessity of additional earthquake action in the horizontal seismic calculation of a water tower has been verified by an example presented in the end of the paper.
