摘　　要：黄土具有很强的结构性,是一种不同于其他土体的地质材料,其结构特性的研究越来越受到关注并由定性向定量化转变。黄土结构性研究具有重要的工程价值和理论意义。通过大量与黄土结构性相关的文献检索与分析,本文首先回顾了黄土结构性定量化的研究进程;从结构性影响因素、本构关系和与湿陷性关系等方面总结了近年来黄土结构性定量化研究的成果。最后,针对黄土结构性定量化研究中仍存在的不足,展望并探讨了今后的研究方向。Loess which has a strong structural property is a kind of geological material.It is different from other soils in physical and mechanical behaviors.Recently the study of its structural property,from qualitative to quantitative,has drawn more and more attention in the engineering and geo-mechanical field.Structural research of loess is of great practical significance.On the other hand,after presenting an overview of the published literature on structural behavior of loess,including influence factors on structural behavior of loess,constitutive relation,and collapsibility and so on,the quantitative research progress on mechanical behaviors of loess is reviewed.Considering the lack of knowledge on structural behavior of loess from quantitative research,this paper discusses and suggests the future studies on it.
