Abstract

Municipal solid waste (MSW) is a special kind of porous media with a large amount of degradable composition. A biochemo-hydro-mechanical (BCHM) coupled model is presented with a consideration of MSW degradation characteristic different from traditional soils. The cellulose anaerobic degradation model is used to describe landfill gas and leachate generation during biodegradation. MSW deformation behavior and seepage characteristic are expressed by considering solid skeleton soften due to biodegradation. The seepage and settlement behaviors in a hypothetical landfill with high kitchen waste content are simulated by the presented model. The results demonstrate the problems in landfills with high kitchen waste content, such as leachate mound, leachate-gas movement mutual retardation, and significant closure settlement.
