摘要
以中国东北地区某垃圾填埋场防渗处理为例,通过对该地区地基渗透性的分析,选择了恰当的防渗处理方法,经防渗处理设计计算分析,指出在淤泥质粉质粘土中掺入7.5%钠质膨润土,处理厚度不小于1.5 m,能够满足规范规定的单层防渗结构防渗条件,进而达到降低成本的目的。
Taking the rubbish landfill seepage resisting treatment in northeastern region as an example,through analyzing the foundation seep-age,the paper selects suitable seepage resisting methods. Through seepage-resisting treatment design and computation analysis,it points out that：mixing 7. 5% of sodic expansive soil in slurry powder cohesive soil will achieve less than 1. 5 m of treatment thickness,which can meet single-layer seepage-resisting structure seepage-preventing conditions and to achieve the goal of reducing cost.
