基于粉煤灰改性粘土的垃圾填埋场防渗层的实验研究

Experimental Research on Landfill Impermeable Layer Based on fly ash Modified Clay Soil

本文主要针对垃圾填埋场防渗层的问题进行分析,重点阐述了经过掺入粉煤灰后的粘土液限、塑限、最大干密度和最优含水率测定方法.本文的实验结论为垃圾填埋埋场改性材料粉煤灰的选择提供了参考与借鉴.

The landfill impermeable layer geotechnical mechanics problems are analyzed in the paper. The fly - ash modified clay liquid limit and plastic limit of determination test and modified clay maximum dry density and opti- mum moisture content of fly ash determination test are demonstrated. In this paper, the experimental conclusion for landfill field modification material provides a reference and model choice of fly ash.
