经典弹塑性力学体系下岩土材料的本构方程

CONSTITUTIVE MODEL FOR GEOMATERIALS WITHIN CLASSIC ELASTOPLASTIC THEORY

  • 摘要: 剑桥模型,修正剑桥模型以及近年来出现的适用于砂土和黏土的统一硬化模型在岩土工程中有重要的科研和实用价值. 在经典弹塑性力学框架下重新推导了以上这些岩土材料本构方程,对岩土工程中常用的本构模型和经典弹塑性理论框架下的岩土本构模型进行了对比,将两个体系下的相关量建立了联系.

     

    Abstract: Original Cam-clay model, modified Cam-clay model and a newunified constitutive model for both clay and sand are widely used inboth research and engineering applications. Within the classicelastoplastic theory, those constitutive models for geomaterials arededuced afresh in this paper. Comparisons between those constitutive modelswithin the classic elastoplastic theory and thepractical geotechnical engineering are made. The relationships betweenthe corresponding variables and parameters are obtained.
