Prediction Analysis of Water Infiltration Effect on Landfill Gas Transport

摘要：

Based on the unsaturated seepage theory and LFG generation and transport character, the coupling numerical model for describing LFG flow with water has been developmented in landfill. The variation of water pressure and saturation in the process of infiltration and distribution of gas pressure and production is presented by the coupling model. The numerical results show: LFG movement to ambient infiltration zone and surface is due to gas pressure persistent arised. Gas displacement by water is the mainly characteristic in infiltration process.
