摘　　要：通过湿陷性土发生湿陷的物理和化学过程分析,将其成因和机理归纳为内部原因和外部原因,并结合规范对湿陷土的湿陷系数和湿陷量进行计算,依据湿陷量对土层的湿陷性等级进行划分,根据湿陷性土的特点分析了湿陷性土地基处理中遇到的困难,给出常见的湿陷土处理方案。Through the analysis of the physical and chemical process of collapsible soil,the causes and mechanisms of collapsible soil are summarized as internal causes and external causes.According to the criterion,the coefficient and amount of collapsibility of the soil were calculated,and the level of collapsibility of the soil layer was divided according to the amount of collapsibility.According to the characteristics of collapsible soil,the difficulties encountered in the treatment of collapsible soil foundation are analyzed,and the common treatment schemes of collapsible soil are given.
