Soil - rock - mixture is a typical porous medium , and its seepage is closely related to the particle - size , void ratio and particle shape 土石混合體屬于典型的多孔介質(zhì),其滲透特性與顆粒的大小、孔隙比及顆粒形狀關(guān)系密切。
Based on the lab orthogonal tests , using self - manufactured constant head permeameter , the effect of gravel content , void ratio and particle shape on the coefficient of permeability of soil - rock - mixture was studied 本文采用室內(nèi)正交實(shí)驗(yàn),利用自制的常水頭滲透儀,研究了礫石含量、孔隙比和顆粒形狀3個因素在不同水平下對土石混合體滲透系數(shù)的影響。
Based on the consolidation mechanism analysis of the warping clay under osmotic pressure , a finite strain osmotic pressure consolidation equation , of which the excess pore - pressure or void ratio was selected as dependent variable , was derived 首先,通過分析滲壓作用下的淤填粘土的固結(jié)機(jī)理,推導(dǎo)出以超孔隙水壓力,孔隙比為控制變量的有限應(yīng)變滲壓固結(jié)微分方程。
