摘　　要：基于湿陷性黄土特殊性对工程建设活动影响的情况,结合已有的研究成果,从内因和外因方面分析了影响黄土湿陷性的因素,黄土微观结构特征是其湿陷的内在因素,起决定性作用,水和应力是外在因素,起诱发作用。黄土发生湿陷的机理是黄土在水和力的作用下,其特殊的粒状体架空结构体系发生破坏、孔隙坍塌、颗粒发生结构重组。Based on the collapsible loess particularity influence on engineering construction activities, combined with the existing research results, interior and exterior influencing factors of the loess collapsibility were analyzed. Microstructure characteristic of loess was the interior factor and was a decisive role, water and stress were the exterior factors and had the subordinate function to the loess collapsibility. The mechanism of loess collapsibility was the granular skeleton overhead structure being destroyed, the pore being collapsed and the particles were rearranged under the coordinate action of water and force.
