成都地铁11号线暗挖隧道瓦斯监测体系设计与管理

Design and Management of Gas Monitoring System for Underground Tunnel of Chengdu Metro Line 11

在成都地铁11号线暗挖段高瓦斯隧道建立系统自动监测与人工监测相结合的隧道瓦斯监测体系,根据实测数据对该隧道进行瓦斯防控效果分析,并给出了相应的瓦斯超限处理措施。结果表明,这种"人机结合"的监测体系在该暗挖隧道作用明显,有效保证了隧道的安全施工。

A tunnel gas monitoring system combining automatic monitoring and manual monitoring was established in the high-gas tunnel in the underground excavation section of Chengdu metro line 11.The gas prevention and control effect of the tunnel was analyzed according to the measured data, and the corresponding measures to deal with gas overrun are given. The results show that this kind of "man-machine combination" monitoring system has obvious effect on the underground excavation of the tunnel and effectively ensures the safe construction of the tunnel.
