应力空间岩土本构模型的三维图像

本构模型的三维图像对于全面掌握本构理论具有十分重要的意义,然而现有文献提供的三维模型图像要么粗糙要么不成系统,且目前还没有学者系统地进行过本构模型三维图示化的工作。因此,在简要总结现有本构理论的基础上,对常用的大多数岩土材料本构模型进行了三维图示化,它们对于进一步完善本构理论具有积极的指导作用。

The 3D images of geotechnical constitutive models in the stress space

The visualization of three dimensions (3D) for geotechnical constitutive models plays an important role in mastering the theory of constitutive models entirely. However, the current 3D images provided biny various literatures are either imprecise or unsystematic. So far as the author knows, few has been engaged in the representation of 3D for constitutive models, thereby on the base of outlining the current constitutive theories, this paper provides the 3D images of most common geotechnical constitutive models by computers, some of which have never appeared in published papers. These images can promote the development of constitutive theory.
