六盘山隧道2号斜井穿越含气地层施工建议方案

Suggestions Construction Project of Inclined Shaft Cross Gas Stratum of Liupan Mountain No.2 Tunnel

在隧道施工过程中,虽较少遇到高浓度的硫化氢有毒气体,但仍要重视施工安全。简要介绍了六盘山隧道的工程概况,详细介绍了现场及检测情况,分析了室内外检测试验结果,提出了六盘山隧道硫化氢有毒气体的防治对策。

In process of tunnel construction, construction safety should be valued, although less toxic gases encountered high concentrations of hydrogen sulfide. The paper was briefly introduced project generalization of Liupan Mountain tunnel, and specifically introduced site and inspection situation. Finally, the paper was analyzed results of indoor and outdoor inspection, and put forward countermeasures of preventing poisonous gas of hydrogen sulfide.
