硫化氢是一种有毒有害气体，隧道穿越的地层中含有硫化氢，不仅威胁着施工人员的身体健康及生命安全，也影响着以后的运营安全。结合玉峰山隧道含硫化氢地层的施工实践，介绍该种地层的概况、硫化氢气体的特点和危害、处治总体思路、施工废水处理方法等，对具体施工技术措施，包括加强通风、预先钻孔排放、注浆封闭、自动检测报警等进行了详细阐述，为含硫化氢气地段的隧道施工积累了经验。

Sulfureted hydrogen is a toxic gas. If tunnels have to cross sulfureted hydrogen contained ground, the health and safety of the tunneling workers and the operation safety of the tunnels will be threatened. Based on the construction experience of Yufengshan tunnel in sulfureted hydrogen contained ground, the authors present the general information of this kind of ground, the characteristics of sulfureted hydrogen, the sulfureted hydrogen treatment principle and the waste water treatment method. The authors place their emphasis on the presentation of the technical construction measures in detail, including strengthening the ventilation, prereleasing the gas by drilling boreholes in advance, sealing off the gas by grouting and automatic detecting and alarming. This paper can provide reference for the construction of tunnels in sulfureted hydrogen contained ground in the future.
