摘　　要：填埋场竖向扩建飞灰填埋库区面临因整体沉降、不均匀沉降带来的中间衬垫系统设计难题。通过梳理沉降计算方法,提出一种具有12层结构的中间衬垫系统优化结构,该结构能够同时起到防渗隔离、抵抗不均匀沉降和导排底部填埋气的作用,与浙江省某填埋场的中间衬垫系统相比具有优越性。The vertical expansion of landfill sites for fly ash disposal faces challenges in the design of intermediate lining systems due to overall settlement and uneven settlement.By reviewing the settlement calculation methods,an optimized intermediate lining system with a 12-layer structure was proposed,which could serve multiple functions of preventing seepage and isolation,resisting uneven settlement,and draining landfill gas from the bottom.Compared to the intermediate lining system of a landfill in Zhejiang province,this structure demonstrated superiority.
