摘　　要：本文从黄土的微观结构特征出发,分析了黄土湿陷时内部结构的变化和变形累积效应。以内时理论为基础,限于考虑黄土湿陷的体积变形,建立了宏观内时本构模型。较深入揭示了黄土湿陷变形机理及演变过程。From the view point of mierostructural features of loess,the changes of inter structure and the accumuated deformation effects of collapsing loess are analysized. Besed on the endoehronic theory and giving consideration only to the volume collapsing deformation, a maero-endochronic structive model is established. The mechanism and process of loess collapsing are brought to light to a certain extent.
