摘　　要：采用俞茂宏统一强度理论分析了厚壁圆筒和厚壁球壳的极限荷载 ,得出了统一解形式。利用此解可以合理地得出不同材料的相应解 ,它既可以适用于拉压强度相等的材料 ,也可以适用于拉压强度不相等的材料 ,并且能充分发挥材料性能 ,从而减轻结构重量 。This paper presents a new method to calculate the limit load of thick wall cylinder and thick wall spherical shell based on Yus Unified Strength Theory and a Unified solutions are obtained. The corresponding solutions of different materials can be got from it. The Unified solution can not only be used to fit the properties of the materials with different tension pressure strength but also the ones with equal tension pressure strength, makes full use of the properities of the materials so as to reduce the weight of the structure. The result is of much importance in engineering and economy.
