| 摘 要： | In present engineering practice of landfill gas pollution control and its recovery, technical parameters such as extraction flow and radius of influence of a extraction well must be determined by field tests. A mathematical model for LFG migration under a vertical extraction well is established, which comprehensively reflects affects of several parameters including LFG generation rate, extraction flow, air permeability, buried depth of a extraction well and features of the cover layer. By using the model, pressure distribution of LFG around a vertical extraction well in a landfill can be calculated, the radius of influence of the well can also be determined.
