摘要： 隧道富水断层破碎带常发生突水突泥灾害，给施工安全带来极大威胁，需要制定一套能有效降低灾害影响的处治技术和超前地质预报对策。结合北岭山隧道工程实例，首先从地质条件和施工组织两方面分析突水突泥灾害形成原因，然后根据工程类比和经济技术比选，确定采取堆渣挡护、注浆加固、塌腔回填、小管棚进洞等处治措施，最后,针对富水断层破碎带地质特性，通过研究比较几种常用的地质预报技术，提出由TSP与地质雷达联合探测、超前水平钻孔辅助探水相结合的综合地质预报对策，所得结论对类似工程具有一定的借鉴和指导意义。

Abstract: The groundwater  and mud rush are the frequently encountered geohazards in the excavation of Beilingshan Tunnel. The common reasons that resulting in these geohazards are summarized. Conventional mitigation measures, such as, debris retaining dike, reinforcement by grouting, cavity backfill, small perforated pilot pipe grouting are also introduced in the paper. For the Beilingshan Tunnel project. The site specific geohazards prediction method was proposed for the site geologic condition with rich groundwater and broken rock mass.
