Optimized Design of Intermediate Lining Systems for Vertical Expansion of Fly Ash Landfill Areas
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.
