摘要
本文主要讨论了垃圾填埋场中经粉煤灰改性粘土的防渗层开裂性能问题,分析了填埋场中改性材料的选择并提出具体技术路线,同时分析了粘土衬里破坏机理,最后采用实验方法验证了基于粉煤灰的改性粘土防开裂性能,数据表明经过改性后的粘土有效提高了天然粘土的防开裂能力,为垃圾圾填埋场中改性粘土防渗层工程应用提供了参考.
In the paper the cracking performance of the anti-seepage layer of the clay modified by fly ash in the landfill site is discussed,the selection of the modified materials in the landfill site is analyzed and the specific technical route is proposed.At the same time,the damage mechanism of the clay lining is analyzed.Finally,it verifies the anti-cracking performance of the modified clay based on fly ash by using the experimental method.The data shows that the modified clay effectively improves the anti-cracking ability of the natural clay,which provides a reference for the engineering application of the modified clay anti-seepage layer in the landfill site.
