摘要
为了解决铁路隧道施工及运营期间有害气体H2S的危害,通过对H2S产生原因、隧道内分布特征和危害情况的分析,采用工程类比和理论计算的研究方法,得出施工期加强超前探测、加强通风稀释和制定专项劳动保护措施,运营期采用水气分离排放的处理方案,从而确保隧道施工和运营安全。
The causes,distribution characteristics and damage of H_2S to railway tunnel construction and operation are analyzed. The engineering comparison and theoretical calculation are carried out. A series of technologies,including strengthening advance detection,strengthening ventilation and making professional labor protection measures during tunnel construction and water-gas separation discharge method during tunnel operation,are adopted. The safety of tunnel construction and operation can be guaranteed by using above-mentioned technologies.
