Abstract

Abstract

The heavy metal tailing samples were taken from tailing pond and landfill site of wastes, which were then mixed with typical uncontaiminated soil.The heavy metal contaminated samples with different incorporation ratio, different density and ages were prepared.Under their respective optimum moisture content, direct shear test and the compaction test were done in order to study the effect rules of compaction and strength shear by heavy metal pollution.The results showed: 1) Heavy metal pollution affected the compaction characteristics of soil.Mn had a weak impact on the soil.Pb, Zn, Cd, and Cr had great impacts on the soil, the maximum dry density of soil increased, optimum moisture content decreased with the different incorporation ratio increasing;2) with the degree of consolidation increasing, cvalue gradually increased, value decreased;3) the diffusion effect on the mechanical characteristics of soil was a slow process, cvalue gradually decreased, and value increased with time;and 4) with the increasing of concentration of heavy metal, cvalue gradually increased, and value decreased.
