摘要
通过对穿越F2断层的馒头山隧道施工实践,归纳、分析了穿越断层破碎带时借助地质超前预报手段,根据围岩情况适时调整施工方案和多种支护技术的综合应用,取得良好效果,对同类工程施工有借鉴作用。
Through construction practice of Mantou Mountain Tunnel crossing F2 fault,it is summarized that by means of advanced geological forecast when crossing fault fracture zone,proper adjustment of construction program according to surrounding rock condition and comprehensive application of multiple supporting techniques,it have achieved desirable result,which can be reference for the similar engineering construction.
