| Abstract: | Many factors have influence on permeability of coarse-grained soil. By the results of seepage tests and byusing different test conditions, the paper studies on the influence of coarsegranular soil dry density ρd, fines content P5, void ratio e and nonuniform coefficient Cu to the permeability coefficient, analyzesthe relation between coarse granular soil dry density ρd, fines content P5, void ratio e, nonuniform coefficient Cu and permeability coefficient. Thus there isa relational expression between coarse granular soil dry density ρd, fines content P5, voidratio e, nonuniform coefficient Cu and permeability coefficient. |
