摘要
以不同程度铅离子污染黄土为研究对象,通过酸碱度试验和无侧限抗压强度试验,测试铅离子污染对黄土基本工程性质的影响。结果发现,随着铅离子浓度的增大,土体的碱性降低酸性增强,液塑限均低于素土,无侧限抗压强度整体呈现增大的趋势。研究结果对污染土工程治理具有一定的借鉴作用。
Taking lead ion-contaminated loess as the research object, the effect of lead ion pollution on the basic engineering properties of loess was tested through pH test and unconfined compressive strength test. It was found that with the increase of lead ion concentration, the alkalinity of the soil decreased and the acidity increased. The liquid-plastic limit was lower than that of plain soil, and the unconfined compressive strength showed an overall increasing trend. The research results have a certain reference effect on the engineering treatment of polluted soil.
