摘　　要：首先论述混凝土本构模型研究的重要性,并说明损伤力学理论较适于构建混凝土本构模型;然后对损伤变量的定义、损伤演化方程的确定、损伤本构模型的建立以及如何考虑不可恢复变形与率效应进行较为详细的论述;最后就混凝土损伤本构模型的发展方向提出了看法。First,the importance of researches on concrete constitutive models was presented.The theory of damage mechanics was shown to be suitable for the establishment of concrete constitutive models.Then,the definition of damage variables,the determination of damage evolution equations,the establishment of concrete constitutive models as well as how to consider the irreversible deformation and strain rate effect were discussed.Finally,some opinions about the development direction of concrete damage constitutive models were proposed.
