摘　　要：为更好地定义和理解毕肖普(Bishop)应力,针对非饱和土本构模型有效应力研究中存在的问题,提出了广义有效应力定义框架,并与传统Bishop应力定义框架做了比较,探讨了基质吸力、粘固作用、硬化过程。In order to accurately define and understand the Bishop＇s stress,the definition framework of generalized effective stress is put forward by considering the shortcomings of constitutive model of unsaturated soil.And then it compares with the traditional definition framework of the Bishop＇s stress.Finally,the matric suction,cementation action and hardening process are discussed.

关 键 词：广义有效应力 毕肖普应力 基质吸力 本构关系 硬化参数
