摘　　要：概括了建立混凝土动力损伤本构模型的基础理论,简述了应用这些基本理论在建立混凝土动损伤本构方面的应用,对相关研究的特点和不足做了分析,为进一步建立科学合理实用的混凝土动损伤本构提供较全面的理论总结和前瞻性启发,对相关理论的发展趋势做了展望,为这方面的工作提供指导.Key theories and approaches on establishing outlined, which include continuum mechanics, damage dynamic damage constitutive model for concrete are mechanics, classic plasticity mechanics, continuum thermodynamics containing internal variable theory, micro-mesomechanics and endochronic theory. Constructing scientific and reasonable dynamic damage model for concrete requires knowing those theories well. Brief description has been made on applications and their characteristics as well as shortcomings. The trends for these studies are previewed.
