摘要
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 expansionshrinkage characteristics and the internal structure and mineralogical and chemical composition of the Middle Pleistocene soil closely related with the geologic hazard have systematically been analysedThe 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
