摘　　要：本文简要介绍厚壁圆筒体厚度计算的两种方法:按拉美公式和Tresca屈服准则进行设计,并对采用两种计算方法得到的结果进行分析、对比,指出厚壁圆筒体厚度应按Tresca屈服准则进行设计,可以更充分地发挥材料的承压潜能,是更为合理的设计。同时对圆筒体上常用的三种开孔补强方法:等面积补强法、应力分类法及极限载荷法进行简要介绍,并通过算例对按照三种补强方法计算得到的结果进行分析与总结,指出每种方法在计算时的优劣势,对以后的工程设计起到一定的指导作用。This paper briefly introduces two methods for calculating the thickness of thick wall cylinders: the design is according to the Lame formula and Tresca yield criterion,and the results obtained by the two calculation methods are analyzed and compared. It is pointed out that the thickness of thick wall cylinders should be designed based on Tresca yield criterion,which can give full play to the pressure potential of the material and is a more reasonable design. At the same time,three commonly used opening reinforcement methods on cylindrical bodies: equal area reinforcement method,stress classification method and limit load method are briefly introduced, and the results calculated according to the three reinforcement methods are analyzed and summarized through calculation examples. The advantages and disadvantages of each method in calculation are pointed out in order to play a guiding role in future engineering design.
