摘　　要：采用俞茂鋐统一强度理论分析了厚壁圆筒的极限荷载，得出统一解形式，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．This paper presents a new method tocalculate the limit load of thick wall cylinder underhigh pressure based on Yu's Unified Strength Theory and a Unified solution are obtained. The Unifiedsolution can be used to both the materials with different tension-pressure strength and the ones withequal tension-pressure strength.

关 键 词：拉压强度 统一强度理论 厚壁圆筒 极限荷载
