摘要
当隧道处于高地应力区时,在施工过程中容易发生岩爆突发性工程事故,直接威胁到现场施工人员和施工机械设备的安全。为了减少岩爆工程事故的发生,以山西省公路第二长隧道——宝塔山特长隧道(长10.48km)为工程实例,介绍了隧道穿越岩爆地层的设计及施工防治措施,可供同类工程借鉴和参考。
When tunnel is located in highland with tension,it is easy to occur sudden rock fall accident during construction which would directly threatens safety of builders and equipments. In order to minimize rock fall accidents, the second longest tunnel in Shanxi Province-Baotashan Tunnel, which is 10. 48km long, is taken as project background in the paper, prevention and corresponding treatment measures for tunnel crossing rock fall stratum in the design and construction are introduced, which could will provide some reference for similar projects.
