摘要
《“十三五”全国城镇生活垃圾无害化处理设施建设规划》到2020年,基本实现生活垃圾全焚烧,原生垃圾零填埋,届时,生活垃圾填埋场面临生态治理,焚烧厂产生的飞灰亟需填埋处置,设计将飞灰填埋场建于生活垃圾填埋场可有效解决该问题并节约土地空间。但考虑到生活垃圾的高压缩性,在上部飞灰堆载作用下,下部垃圾堆体极易发生不均匀沉降,引起飞灰堆体及垃圾堆体的失稳滑移,并导致飞灰库区底部防渗膜破坏。因此,评估飞灰填埋库区是否可建于生活垃圾堆体上应事先进行稳定性分析。针对一个拟建于生活垃圾堆体上的飞灰库区项目进行稳定性分析,评估其可行性。
By 2020,the 13th Five-Year Plan for the Construction of National Urban Domestic Waste Harmless Treatment Facilities will basically realize the complete incineration of municipal solid waste(MSW)and zero landfill of raw waste.At that time,the landfill site of MSWwill be facing ecological control.The fly ash produced by the incinerator will need to be filled and disposed.The fly ash landfill site will be designed to be built in the landfill site of MSW,which can effectively solve this problem and save land space.However,considering the high compressibility of MSW,the uneven settlement of the lower MSW dump is easy to occur under the action of the upper fly ash surcharge,which causes the unstable sliding of the fly ash dump and the MSW dump,and the destruction of the impervious membrane at the bottom of the fly ash reservoir area.Therefore,the stability analysis should be carried out in advance to evaluate whether the fly ash landfill area can be built on the domestic waste dump.Finally,the stability of a fly ash reservoir project to be built on domestic waste dump was analyzed,and its feasibility was evaluated.
