| 摘 要： | 该文对由顶板、底板和圆柱形池壁组成的圆形贮液池在轴对称荷载作用下进行内力分析，池壁上、下端的圆周视为弹性嵌圆结点，用圆柱壳理论计算池壁的固端弯矩，用薄板弯曲理论计算顶板和底板的固端弯矩，从而求得上、下2个结点的不平衡力矩，然后用弯矩分配法对结点的不平衡力矩进行无数次分配传递，求得无数次分配弯矩和传递弯矩之和，得闭合解。文中给出了算例。

| Abstract: | In this paper cylindrical pools with upper and bottom plates under the action of symmetric loads are discussed.The circular edges of upper and bottom plates are considered as two elastic joints. The cylindrical walls are studied and the fixed end moments are obtained by using the theory of shells. The upper and bottom plates are studied and the fixed end moments are also obtained by using the theory of thin plate. The unbalanced joint moments are distributed and carried over infinitely to obtain closed solutions which is expressed by distribution factors and carried over factors.Examples are given in the paper. |
