结构性粘土研究进展

通过对结构性粘土的研究，可以掌握天然土受荷过程中的变形破坏过程，从而为考虑土结构性的结构物的设计、地基加固等提供依据。近年来随着高、深和大型建筑的兴建，结构性粘土的研究变得尤为重要。从结构性粘土的微观变形机理、结构性土样的制备、土工特性和数学模型等几个方面，介绍了国内外学者的研究进展，认为进行原位测试、结构性土样的制备及细观结构参数的量测方法、考虑细观结构的数值方法和建立考虑微观变形机理的宏观本构模型是进行结构性土研究的发展方向。

Advance in researches on structured clay

The deformation and failure process of natural soil under loading can be obtained by research on structured clay ,on which the design of construction and soil improvement can be based when the structural influence is considered. With the construction of high, deep and great buildings, the research on the structured soil has recently become more and more important. In this paper, the researches of structured clay on micro deformation mechanism, artificial preparation, civil engineering behavior and numerical models are introduced. Processing in situ test, artificial preparation of structured soil, measuring methods of meso-structural parameters,numerical methods considering meso-structure and establishing macro-constitutive models considering micro- deformation mechanism are the important problems of study on the structured soil.
