黏性细粒土基床系数影响因素多元回归分析

Multiple regression analysis of the influence factors of coefficient of subgrade reaction of clayey fine-grained soil

考虑了孔隙比、含水率、塑性指数三种主要内在因素对黏性细粒土基床系数的影响,并建立了其多元回归方程及标准化回归方程,分析了基床系数对各因素的敏感性,为合理确定黏性细粒土基床系数提供了理论依据。

This paper considered the effect of three main factors such as void ratio,moisture content and plasticity index on coefficient of subgrade reaction of clayey fine-grained soil,and established the multiple regression equation and normalized regression equation. This paper also analyzed the sensitivity of coefficient of subgrade reaction to various factors,and provided theoretical support for determining the coefficients of the subgrade reaction of clayey fine-grained soil reasonably.
