【摘要】 根据南京河西地区粉质粘土的土工试验资料,对其物理、力学指标进行统计分析,研究土体的力学指标与物理指标的变异性及相关性,采用回归分析的方法对土的物理和力学性质指标进行线性回归分析,给出相应的数学回归方程式和相关系数。结论可作为区域性地基基础可靠性设计相关参数选取的依据。更多还原

【Abstract】 Based on the testing data of the silty clay in the Hexi area of Nanjing,physical and mechanical indexes of the clay were analyzed and the index variability and their relationship between each other were studied.A method of linear regress analysis is adopted to the indexes.This paper statistically analyzes the variability differences,correlation and regression between physical and mechanical indexes.The results can be used as the related parameter selection basis of regional foundation reliability design.更多还原
