Estimation method of saturated surface dry specific gravity and dry specific gravity of graval grain for rectifying maximum dry density 砾石颗粒干比重及饱和面干比重的估算方法&应用于最大干密度校正
There is a close relation between saturated surface dry specific gravity ( Gs 3 ), dry specific gravity ( s 2 ) of graval grain and its mineral composition, and void ratio, and void feature. 砾石颗粒的饱和面干比重(Gs3)、干比重(Gs2)与其本身矿物成分、孔隙比、孔隙特征有着密切关系。
