摘要
介绍了国内外垃圾填埋场防渗技术的研究现状及存在问题。借鉴发达国家的应用经验和研究成果,对我国垃圾填埋场的结构设计进行分析,包括填埋场防渗衬垫的选材,结构布置和施工方法,填埋场封顶系统的设计,渗沥液收集与排放系统和填埋气收集与处理系统的设计。预估填埋场渗沥液渗漏量的计算方法,分析了渗沥液在压实黏土、土工膜中的渗漏特点,提出了对各种防渗衬垫的优化布置方法。
Research status and existing problems of impermeable technology in waste landfill sites at home and abroad were introduced.Using engineering experience and research results in developed countries, structural design of waste landfill sites in China was analyzed, including material selection of impermeable liners in waste landfill sites, construction layout and construction methods, design of cover system in waste landfill sites, and design of leachate collection drainage system and landfill gas collection treatment system.Computational method for estimating percolation quantity of leachate in waste landfill sites was presented.Percolation characters of leachate in compacted clay and geomembrane were analyzed.The optimal designing methods of different impermeable liners were put forward.
