上部结构与地基基础共同作用下的土的本构模型综述

REVIEW OF THE SOIL CONSTITUTIVE MODEL UNDER THE INTERACTION BETWEEN UPPER STRUCTURE AND FOUNDATION

土的本构模型即表示土体在受力状态下的应力应变关系。自20世纪初以来,国内外学者对上部结构与地基基础共同作用下的土的本构模型进行了大量的研究,整理这些本构模型对工程实践及以后的研究有着重要的意义。文章基于以前的上部结构与地基基础共同作用下的土的本构模型的研究,简述了土的本构模型的发展,列出了几种应用广泛的土的本构模型。最后对土的本构模型的发展趋势作了展望。

Soil constitutive model is to point to soil＇ s stress-strain relationship. Since the early twentieth century, scholars both at home and abroad have made a large number of research of the soil constitute model under the interaction between upper structure and foundation, It has vital significance to clean up these constitutive madels for engineering practice and the future research. This article, based on the previous research on the soil constitutive model under the interaction between upper structure and foundation, describes the development of soil constitutive model simply T-hen lists several widely used soil constitutive models. At last, prospective development of the soil constitutive model are presented.
