摘　　要：目前实际工程中通常采用现场抽气试验的方法确定垃圾填埋气收集系统的相关技术参数 ,这种方法不能对影响抽气效果的因素综合分析并加以优化。本文利用竖井抽气条件下填埋气压力分布模型 ,分析讨论了抽气系统各参数对对抽气效果的影响 ,提出了垃圾填埋场填埋气竖井收集系统的抽气量、抽气井影响半径、抽气井埋深的优化设计方法 。In present engineering practice of landfill gas pollution control and its recovery, engineering parameters are usually determined by field tests. By using the mathematical model for LFG pressure distribution under a vertical extraction well, method of optimum design of landfill gas collection system with vertical extraction wells was discussed in this paper, including the determination of LFG extraction flow, radius of influence of extraction well, and the buried depth of the well.
