昆明市南市区软土内摩擦角与各物理指标之间的相关关系分析

选取昆明市南市区27个软土场地,通过大量的土工试验,对其参数进行分析,得出软土内摩擦角与各物理指标之间的相关关系;并得出相应的数学回归方程式和相关系数。结果表明:孔隙比e、饱和度S r与内摩擦角φ值存在负相关关系;液限ωL、液性指数I L与内摩擦角φ值呈现正相关,相关系数为0.749。

The analysis of the correlativity between the internal frictional angle and physical parameter of the soft soil in the south city,Kunming,Yunnan Province

Twenty seven areas, which are constituted by soft soil, in the south city, Kunming, Yunnan Province have been studied in order to get the correlativity between the internal frictional angle and physical parameter, and putforward the empirical formula between them, which will provide more or less guiding for ascertaining the shearing strength of foundation soil.It turned out that there are six factors related well with the internal frictional angle and the correlation coefficient is 0.749.
