摘　　要：就传统塑性位势理论与广义塑性位势理论(考虑和不考虑应力主轴旋转两种情况下)进行了系统的综述与比较。两种位势理论就解决金属与岩土变形机制问题均获得了很大的成功(尤其是后者);浅析了广义塑性位势理论遇到的困境和发展前景。The paper gives a systemmetical and comprehensive description and comparation to traditional plasticity potential theory and generalized plasticity potential theory (including two cases:stress main axis revolving or not).The two potential theories offer an answer to question of metal and rock deforming mechanicsm and make great achievements(especially involved the latter). At the same time ,it gives difficult potential and developing prospect involved generalized plasticity potential theory.

关 键 词：位势理论 传统塑性 广义塑性 屈服面
