穿越不良地质路段特长隧道的设计和施工措施

Measures for Design and Construction of Long Tunnel Traversing Adverse Geology

针对穿越不良地质路段的隧道施工难度大、工期长、造价高等问题,以隧道穿越岩爆、煤层和瓦斯等不良地质路段为例介绍了此类工程的设计及施工时的防治措施,重点提到了在岩爆处的设计及施工的关键技术,可为同类工程设计和施工提供借鉴和参考。

Aimed at the problems of tunnel traversing adverse geology such as difficulty in construction, time consuming and high cost, preventive measures for the design and construction of long tunnel in the circumstances of traversing adverse geology such as rockburst, coal seam and gas stratum were introduced. The design of rockburst spot and key technology of construction were stressed, which provides reference for similar projects.
