摘　　要：采用圆柱壳体理论和有限元分析的方法,对贮存高温水的圆形沉淀池壁进行了结构分析。在壁面温差影响下,两种方法求得的池壁结构应力基本一致,验证了用Solsh190单元模拟钢筋混凝土薄壳结构是可行的。利用有限元软件ANSYS的三维热单元和三维结构壳单元对池壁应力状态进行了热-结构耦合数值模拟,研究了在冬季壁面温差最大的情况下池壁应力的分布规律,为池壁结构加固提供了依据。According to the theory of cylindrical shell and the method of finite element analysis, this article completed the structural analysis on the wall of the tank storing hot water. With the effect of the wall temperature difference, the stresses of wall structure solved by two methods were basic consistent. It verified that using Solsh190 to simulate reinforced concrete shell structure is feasible. By using 3D thermal element and 3D shell element of the finite element software ANSYS, the stress state of the wall structure was completed with the heat-structure coupling simulation. This article discussed the wall stress distribution in maximum wall temperature difference in winter and provided a reference for the reinforcement of wall structure.
