摘　　要：采用俞茂宏统一强度理论分别就平面应变和平面应力问题对受压孔洞进行了极限分析，得到了各自的统一解形式。以往的基于Ｔｒｅｓｃａ、Ｍｉｓｅｓ、双剪屈服准则以及ＭｏｈｒＣｏｕｌｏｍ ｂ 强度理论的极限解均为本文统一解的特例。此解可以适应于广泛的不同性质的各类材料。In this paper, Yu Maohongs Unified Strength Theory is used to analyze the ultimate load of a thin plane with a hole and a unified solution is obtained. The solutions based on Tresca, Mises. Twin Shear criterion and Mohr Coulomb strength theory are special cases of the unified solution. The result can be used to fit the properties of different kinds of materials and is of importance in engineering and economy.
