摘　　要：本文把耐压液舱结构看成一弹性整体，先对其进行整体求解，然后再对耐压液舱壳板按具有初始股应力的混合边界问题求解。结果表明：在弹性范围内，本文方法计算值与有限元计算值及实验值吻合较好；在弹塑性范围内，本文对耐压液舱亮板边界约束的处理比文献「l］方法更符合弹塑性状态时其边界约束的真实状况。Regarded as an elastic body, the entire structure of a ballast tank is solved as a whole, then the stress of the shell of the ballast tank is solved as a mixed-boundary problem with initial membrane stress. The results agree well with FEM results and experimental results in the elastic range. In the elasto-plastic range, the treatment of boundary restraint in this paper is better than that of Ref. [1j.
