摘　　要：基于广义位势理论与损伤力学基本原理,对在广义位势理论中土料的损伤过程进行研究,提出广义损伤与狭义损伤的相对概念,从广义位势理论与损伤势函数的角度考虑摩擦材料的损伤与破坏过程,讨论广义位势理论中土料的损伤模型。Based on the generalized potential theory and the basic principles of damage mechanics, the damage process of soil was studied, and the relative conceptions about generalized damage and restricted damage were presented. Then, the damage process of friction materials was considered and the damage model of soil in the generalized potential theory was discussed.
