摘　　要：首先进行了潜艇耐压液舱结构四种应力近似解析法的比较分析；指出了《潜艇强度》中推荐的方法已不适用，黄加强方法被沈丰方法包含，国外的一种方法与沈丰方法典型点计算结果接近，但沈丰方法简单、实用；然后通过沈丰方法与有限元方法计算结果的比较，指出了沈丰方法仅可在结构初步设计时引用；最后，推荐了耐压液舱结构应力近似解析法的具体算式。First, comnparison of four approximate analysis methods for stresses of pressure tank structure of submarine is completed. It is pointed out that the recommendatory method in 《Submarine Strength》 can be not used already; the Huang Jiaqiang method is included by the Shen Feng method; calculating results of typical point stresses obtained by a foreign methd are near in comparison with the Shen Feng method, but the Shen Feng method is simpler and practical. After comparison with the finite element method, it is discovered that the Shen Feng Method can be only used in the initial structure design. Last, concrete formulae of approximate analysis method for stresses of pressure tank structure are recommende.
