摘　　要：某新建的铁路场站工程场址原为建筑渣土消纳场,场地中混有大量生活垃圾。生活垃圾产生的填埋气会对建成后的铁路场站产生安全和环境风险。本文通过钻孔取样,调查了渣土消纳场内生活垃圾含量、分布和产气现状。根据生活垃圾分布不均、大部分处于较稳定状态的特点,提出了针对填埋气控制的覆盖封闭和局部强制导排的环保处理措施,取得了较好的效果,为今后类似工程提供了一定参考经验。A new railway station was building on a waste disposal field,which contained a substantial amount of municipal solid waste.Municipal solid waste could generate landfill gas and thus would cause safe and environmental risk to the new station.In this study,the level,distribution,and gas yield of the municipal solid waste in the filed were investigated.It was found that the municipal solid waste was distributed unevenly but stable.Accordingly,the field was sealed by a designed cover layer and the landfill gas was extracted and piped to a discharge point.This treatment method was successful in controlling the landfill gas and provided a useful reference for other projects.
