| 摘 要： | 采用俞茂宏统一强度理论和统一滑移线场理论对拉压异性楔体的极限荷载进行了分析，得到了统一滑移线解，以往的经典塑性力学的解均为文中解的特例利用此解可合理地得出不同材料的相应解，并能考虑材料的拉压异性和中间主应力效应文中还探讨了所得统一解在岩土工程中的应用

| Abstract: | In this paper, the unified strengh theory(Yu,1991) and unified slip line field theory(Yu Yang, 1997) are used to analyze the ultimate load of a strength differential wedge, and a unified solution which takes account of the strength difference effect and the intermediate main stress effect is obtained. The solutions based on the theories before are special cases of the unified solution. The corresponding solutions of different kinds of materials can be got from it. Finally, its application in geotechnical engineering is discussed. |
