  • A mathematical model of landfill gas migration was established under presumption of the effect of gas slippage.The slippage solutions to the nonlinear mathematical model were accomplished by the perturbation and integral transformation method.The distribution law of gas pressure in landfill site was presented under the conditions of considering and neglecting slippage effect.Sensitivity of the model input parameters was analyzed.The model solutions were compared to observation values.Results show that gas slippage effect has a large impact on gas pressure distribution.Landfill gas pressure and pressure gradient considering slippage effect is lower than that neglecting slippage effect,with reasonable agreement between model solution and measured data.It makes clear that the difference between considering and neglecting slippage effect is obvious and the effects of coupling cannot be ignored.The theoretical basis is provided for engineering design of security control and decision making of gas exploitation in landfill site.The solutions give scientific foundation to analyzing well test data in the process of low-permeabilityoil gas reservoir exploitation.
