摘　　要：　由于岩石、混凝土等材料的复杂性,使其峰后本构理论的研究非常困难。国内外许多学者依据多种力学理论建立了各种各样的本构模型。本文在讨论岩石力学本构模型发展理论的基础上,概要介绍了已有的各类本构模型并进行了简单评述,最后指出了其发展趋势。Because of the complexity of rock and concrete, it is difficult to study the contitutive relation of rock and concrete in post-peak area. On the basis of discussing the theory of rock mechanics models, this paper reviewed several constitutive models of rock and concrete and the discussion of models is presented, and the trend of this study is showed.
