在回顾早期黄土湿陷机理研究成果的基础上，概述了黄土湿陷机理的发展历程，从微观结构、数理分析方法、土力学角度和建立本构模型4个方面总结了黄土湿陷机理的研究现状。通过工程实例研究提出了当前黄土湿陷机理发展中存在的问题；并对其发展趋势进行了分析。认为应以黄土微观结构研究为基础，结合先进测试仪器和分析软件，从非饱和土力学的角度出发，采用离散元分析手段，考虑溶盐因素，系统建立各种应力路径下黄土湿陷本构关系，从而完善黄土湿陷机理的研究。这对正确理解和研究黄土湿陷机理具有重大的理论意义和指导意义。

This paper summarizes the development of the loess collapsibility mechanism on the basis of memori-zing the early results,discusses the research status of loess collapsibility mechanism from the aspect of micro-scopic structure,mathematical analysis methods,soil mechanics and constitutive model,and provides some problems in current growth of the loess collapsibility mechanism research combining the project instance and out-lines the development trend of the research.A viewpoint is constructed that the research of loess collapsibility mechanism should be improved by constructing the constitutive relation of loess collapsibility under various stress paths from the aspect of unsaturated soil mechanics using discrete element analysis and considering the soluble salt,combining the advanced instruments and analysis software on the basis of the study of losses microstruc-ture.It has an significant theory and introduction meaning to understand the loess collapsibility mechanism cor-rectly and make a deep research.
