摘要
为解决特长隧道穿越复杂地质的施工难题,以米仓大道项目铁厂隧道工程为依托,采用现场勘查及实时监测等方法,深入分析了铁厂隧道施工中存在的不良地质问题以及工程难点,并从超前地质预报、隧道爆破开挖以及瓦斯检测及通风3个方面提出了复杂地质条件下特长隧道关键施工技术,实现了铁厂隧道的安全、高效施工,为铁厂隧道的顺利贯通提供了技术支撑,也为其他类似工程施工提供了经验参考。
In order to solve the construction problem of super long tunnel crossing complex geology,based on Tiechang Tunnel Project of Micang Avenue Project,the adverse geological problems and engineering difficulties existing in the construction of Tiechang Tunnel are deeply analyzed by means of site investigation and real-time monitoring.The key construction technologies of super long tunnel under complex geological conditions are put forward from three aspects of advanced geological prediction,tunnel blasting excavation,gas detection and ventilation,which realizes the safe and efficient construction of Tiechang Tunnel,provides technical support for the smooth breakthrough of Tiechang Tunnel,and also provides reference experience for other similar projects.
