本文分析了当前国际上土质分类的特点,回顾了国内土质分类状况,为配合制定我国的土质统一分类标准,据江西省建筑设计院历年来在南昌的1227个钻孔、1931筒土试料的有关勘察试验资料,综合绘制成南昌细粒土塑性图,并与美国的统一分类法、我国土工试验规程等之塑性图进行了比较,从而为我国制定细粒土塑性图提供地区性的资料。最后,以我院土质指标绘于塑性图上,可以看出这些点基本上与南昌A线重合。因此,可以初步认为南昌细粒土塑性图对地处长江中游北岸的湖北沙市一带也是适用的。
This paper analyzes the characteristics of the current international classification of soil quality, reviews the status of domestic soil classification, and cooperates with the formulation of China’s unified classification criteria for soil quality. According to Jiangxi Provincial Architectural Design Institute, 1,227 boreholes and 1931 soil samples were sampled in Nanchang over the years. With regard to survey and test data, the plastic map of Nanchang fine-grained soil was comprehensively mapped and compared with the plastic maps of the United States unified classification method and China’s geotechnical test procedures, thus providing regional data for the formulation of fine-grained soil plastic maps in China. Finally, the soil quality index of our hospital was plotted on the plastic map. It can be seen that these points are basically coincident with the A line of Nanchang. Therefore, it can be preliminarily assumed that the plastic map of Nanchang fine-grained soil is also applicable to the northern part of Shashi City in Hubei Province located on the northern bank of the middle reaches of the Yangtze River.
