湖北崇阳城区土体胀缩特性研究

Study on ExpansionShrinkage Characteristics of Soils in Chongyang Town Area, Hubei

针对湖北崇阳县城区某些建筑物（构筑物）发生地面开裂地质灾害问题，根据勘察资料和大量的有关土体工程地质性质试验成果，系统地分析了与灾害密切相关的中更新统残坡积土体（层）的胀缩特性及与其内在的组织结构、矿物组成、化学成分之间的关系，阐述了膨胀土的空间分布特征及其与灾害分布的相互关系，为灾害成因判定和治理提供了科学的依据。

In view of the fact that lots of buildings and ground were broken in Chongyang town area, Hubei, the expansionshrinkage characteristics and the internal structure and mineralogical and chemical composition of the Middle Pleistocene soil closely related with the geologic hazard have systematically been analysedThe spatial distribution of expansive soil and its relation to the distribution of hazard have been discussed This research is specially important to find out the origin of hazard, as well as to control it
