摘　　要：实验表明 ,经典塑性力学难以反映岩土材料的变形机制 ,原因在于经典塑性力学作了传统塑性势假设、关联流动法则假设与不考虑应力主轴旋转的假设。广义塑性力学放弃了这些假设 ,采用了分量理论 ,由固体力学原理直接导出塑性公式 ,它既适用于岩土材料 。It's shown by experiments that the classic plastic mechanics is difficult to reflect the real deformation mechanism of geomaterials.The reason is that the classic plastic mechanics is based on the hypothesis of the traditional potential theory,the hypothesis of the associated flow rule and the hypothesis of not considering rotation of principal stress.The generalized plastic mechahics gives up all these hypotheses and gets all its plastic formulas from solid mechanics directly,so it can be used for both geomaterials and metals.

关 键 词：塑性力学 塑性势 屈服面 广义塑性力学 岩土
