摘要
针对安徽省中部地区一些工程构筑物发生开裂等地质灾害问题,根据勘察资料和大量土体的工程地质性质试验成果,系统地分析了与灾害密切相关的上更新统粘性土的胀缩特性,及与其内在的矿物成份、化学组分及粘粒之间的关系,论述了膨胀土的空间分布特征与膨胀土灾害的关系,从而为灾害的成因判定和治理提供了科学的依据。
In view of the fact that lost of buildings and ground were broken in the middle area,Anhui,the expansion-shrinkage characteristics and the internal structure and mineralogical and chemical composition of the Upper 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.
