针对重金属污染对城市河道淤泥渗透特性的影响,以莆田市渠桥河与樟林河淤泥为研究对象,通过室内固结渗透试验,系统探究Cu2+和Pb2+浓度对淤泥渗透特性的影响规律。试验采用硝酸铅和硝酸铜溶液模拟污染环境,结合变水头渗透法测定不同工况下的渗透系数。试验结果表明:渗透系数随固结压力增大呈指数衰减,随着孔隙比的减小,渗透系数均呈现数量级式递减特征;重金属浓度升高显著降低渗透性,Cu2+浓度为30.9g/L时,渗透系数较未污染土降低1~2个数量级,这是由于液限非线性增长导致;基于液限孔隙比与初始孔隙比建立污染土渗透系数预测模型,经验证其计算值与实测值误差在1/3~3倍范围内。研究成果可为重金属污染淤泥的渗透特性评估及污染场地修复工程设计提供理论依据。
