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.
