摘要
成都经济环线第三绕城高速简阳至蒲江段长秋山隧道属于低瓦斯隧道，施工过程中极易发生瓦斯泄露、突水突泥等地质灾害，如果现场施工安全控制不到位，容易发生重大安全事故，造成严重的经济损失及人员伤亡。长秋山隧道通过人员定位、瓦斯检测与遥测等安全技术措施的改进与革新，确保了瓦斯隧道施工全过程安全受控。
Changqiushan Tunnel on Jianyang-Pujiang section,a component of the third bypass expressway in Chengdu Economy Circle,is a low-gas tunnel,which is highly prone to gas leakage,water burst,mud burst,and other geological hazards,so if the construction site is not protected by appropriate safety control,major safety accidents may happen,giving rise to huge economic or life losses.The construction safety of Changqiushan Tunnel has been kept in control by improving and innovating such safety techniques as personal positioning,gas detection,and telemetry.
