摘　　要：在大型钢筋混凝土冷却塔结构设计方面,由于塔壳受外面风荷载、自重等综合作用,以往研究主要集中于冷却塔壳体及其相关结构方面,而没有对相关的塔内结构进行有效的分析。本文结合典型工程的塔内布置、地质及地震条件,利用有限元分析方法对塔内结构进行了整体性分析,并对比静力计算结果进行了验证,证明了塔内结构整体分析计算结果的有效性。In the field of structure design of natural draft cooling tower, foregone research frequently pay attention to the thin shell structure ,ring beam and shell supports as these structures are related with the wind load, dead weight, and pay little attention to the internal and hydraulic structure by contraries. This paper pay attention to the research on the integer internal and hydraulic structure of the cooling tower with the finite element method, combined with the layout and the engineering geologic condition, earthquake condition. Then the results of the calculation are validated and analyzed, which could conclude that the results of the calculation are trusty.
