摘要
本文从原理上得出了超径粗颗粒土最大干密度为ρdmax=ρdmin+1Aρdo-B(ρdo-ρdmin),较文献[1]中ρdmax=f(ρdmin,Δρd)≈ρdmin+(ρ′dmax-ρ′dmin)进了一步,并据[1]及收集的资料[2]、[3]进行了讨论,提出了相关系数的数字可供设计施工部门初步采用。
From the principle, the paper obtained the formula of maximum dry density of oversize coarse-grained soil, ρ_(dmax)=ρ_(dmin)+1Aρ\-\{do\}-B(ρ_(do)-ρ_(dmin)), which is better than the formula ρ_(dmax)=f(ρ_(dmin),Δρ_d)≈ρ_(dmin)+(ρ~′_(dmax)-ρ~′_(dmin)) in . Based on , and , the paper also puts forward the numerics of correlation coefficient to provide references for design and construction.
