云南省昆明市南市区泥炭质土标贯击数与物理参数之间相关关系分析

摘要

通过大量的土工试验数据,对云南省昆明市南市区泥炭质土标贯修正击数N与物理参数间的相关关系统计分析,并给出相应的数学回归方程式和相关系数.结果表明:标贯修正击数N与液限和孔隙比两因素间存在较好的统计多元线性相关关系.%From the analysis between fixed SPT counts and the physical parameter of the cumulosol in the south district, Kunming,Yunnan Provence, the correlativity between them and putforward the empirical formula and the correlation coefficient is got. Which will provide more or less guiding for ascertaining the bearing capacity of foundation soil. It turns out that there is a good statistical multiple linear relationship among fixed SPT, Natural void ratio and liquid limit and the correlation coefficient is 0. 71.
