摘　　要：采用无弯矩理论(薄膜理论)和有弯矩理论分别对倒锥壳水塔水箱(容积300 m3和500 m3)内力进行计算,分析了水箱上、下锥壳的内力分布情况。计算结果表明:有弯矩理论较无弯矩理论考虑了壳体边缘干扰力的影响,使得计算结果在壳体边缘处有一定差异,但更接近水箱内力的真实情况,可作为倒锥壳水箱内力相对精确的计算方法。研究结果可为同类工程设计提供有益的参考。In this article,internal forces of 300 m3 and 500 m3 inverted cone water tower tanks were calculated by membrane theory and moment theory,and internal force distribution of water tank was analyzed.The results show that the edge interference force makes some differences of internal force distribution of moment theory from that of membrane theory on the edge of tank,but the results of moment theory is closer to the real situation of the tank and moment theory can be used as a relatively accurate method theory for internal force calculation of inverted cone water tank.The results provide a useful reference for the design of similar projects.
