摘要
为研究四川软弱地基物理力学参数相关性,先系统分析四川省内高速公路软弱地基,采用Grubbs法则剔除试验异常数据,得到物理力学指标参数范围值,进而采用统计软件对物理力学指标进行一元回归分析,再对其进行曲线拟合,最终得到相应经验公式以供参考设计使用。
Weak foundation for the study of sichuan physical mechanics parameter correlation, systematic analysis of the sichuan province expressway soft ground first, using Grubbs law to eliminate abnormal test data, parameters of physical and mechanical index value, then USES the statistical software monadic regression analysis was carried out on the physical and mechanical indexes, again carries on the curve fitting, finally get the corresponding empirical formula used for reference in design.
