摘要
大部分垃圾填埋场选在低洼、底部由砂组成的地带 ,开发利用砂土作为填埋场防渗衬垫具有十分重要的意义。本文介绍了砂土中掺和膨润土添加剂对砂土衬垫防渗性能改善的研究方法及研究结果。
A majority of landfill sites are at the low_lying zones composed of sandy soils,and it is important that the sandy soils are used as landfill site liners.This paper describes the research methods and holds that bentonite should be used to improve penetration of the sandy soils liners of the landifill site.
