摘要
粘性土的强度主要受含水量、干容重、孔隙比三因素的影响,它们存在某种不确定关系,用统计学中的回归分析方法,找出它们之间的线性相关关系─—线性回归方程,并证明其回归效果显著.
Water content,dry unit weight and porosity ratio are three major factors influencing claystrength. afire are uncertain relations among them we use regression analysis to find out their linearrelations-linear regression equation and Prove its regression effective.
