    REVIEW ON CURRENT SITUATION OF SOIL STRUCTURAL CONSTITUTIVE MODELS

    • 摘要: 土本构模型的建立是一个重要而又复杂的问题,到目前为止,国内外学者们已提出数以百计的土本构模型,诸多文献也对这些模型进行了评述和归纳。然而这些土本构模型多是在扰动土或砂土的基础上发展和建立起来的,它们难以描述由于土结构性引起的各种非线性行为,其计算结果与实际情况相差甚远。天然土体一般都具有一定的结构性,所以有必要建立考虑土结构性影响的土本构模型。针对这个现实,目前有些学者已基于各种理论和方法,提出了一些可以考虑土结构性影响的土本构模型,并得了较好的应用。但在目前的文献中还很少有对土的结构性本构模型研究进行归纳,基于此,本文简要介绍了一下目前土的结构性本构模型研究现状,并提出了这些本构模型在应用中所存在的问题。

       

      Abstract: It is an important and complex task to construct soil constitutive model.Up to now,there are hundreds of soil constitutive models which have been provided by scholars in China and abroad.These models have been reviewed and documented in many literatures.However,because they were constructed and developed mainly on the basis of disturbed soils or sandy soils,these models are not able to describe the various nonlinear behavior induced by structural property of soil.Subsequently,the calculated results can greatly different with the results of tests performed in situ.Generally,natural soils have structural property.So it is necessary to construct soil constitutive models which can take account of the soil structural property.Some scholars have proposed soil constitutive models that can take account of structural property on the basis of all kinds of theories and methods,and have achieved satisfactory results.But up to now,there are few literatures to give a state of the art review on soil structural constitutive models.Therefore,the paper presents a review on thethe current situation of soil structural constitutive models,points out some issues in use of the soil structural constitutive models
