摘要
In this paper, the inorganic matter density was assumed to be less changeable. A single–dimensional degradation settlement model involves the relationship between density, quality and volume of municipal solid waste while the effect of degradation ratio change has been presented. So the volume change has been acquired with this model. Then, a coupled equation combined with the porosity equation has been established. This equation considered the deformable framework and the landfill gas condensability. The results showed that the pressure in the landfill was influenced by time and organic matter volume percentage, and the pressure gradually diminished with increasing time and organic matter volume percentage.
