摘　　要：在隧道工程的开挖及支护施工过程中,断层及破碎带的存在不仅会加大施工的难度,而且会给施工安全带来较大的安全隐患。因此一旦在隧道施工过程中发现有断层及破碎带存在时,应全面收集工程区域的基础信息资料,并积极采用信息化技术开展波速测试及地面地质调查等,以准确掌握隧道侧壁及掌子面的地质结果特点,并通过超前钻孔等方法来准确预报断层位置规模及岩性特点等,以保证施工的质量安全。The existence of faults and broken zones will not only increase the difficulty of construction,but also bring great risks to construction safety during the excavation and support of tunnel engineering.Therefore,once faults and fracture zones are found in the tunnel construction process,the basic information of the project area should be collected comprehensively,and information technology should be actively used to carry out wave velocity test and ground geological survey,so as to accurately grasp the geological results of the tunnel side wall and face,and accurately predict the fault location scale and lithologic characteristics through advanced drilling and other methods,so as to ensure the quality and safety of construction.
