| Abstract: | This paper proposes two new kinds of liners.A series of columns were used to evaluate the permeability of the new compound soils.Compound soil Ⅰ with the six ratios of lime to the mixture of montmorillonite+silt soil—respectively,0%,0.4%,1%,2%,6%,10%,a liner with sandwich structure and compound soil Ⅱ with four ratios of fly ash to the mixture of montmorillonite+silt clay,were tested in term of their permeability,attenuation ability.We draw the conclusion:the compound soil Ⅰ with the ratio of lime to the mixture of montmorillonite+silt soil,10%,and the liner with `sandwich' structure perform well and cost lowly,which are worth while popularizing. |
