摘要针对高速公路乌鞘岭隧道穿越F4断层破碎带发生的涌水塌方事故，结合地质情况和涌水塌方特征，采用地质勘察、现场实测、理论分析等研究方法，探讨乌鞘岭隧道涌水塌方机制及其导致的初期支护破坏的原因，分析其与断层破碎带围岩、地下水、地质构造之间的联系。本段涌水塌方属于断层破碎带引发的泥砾石型突涌灾害。在此基础上，研究涌水段和掌子面的支护设计及施工组织方案，提出相应的工程对策。现场监测结果显示，处治措施实施后，取得较为满意的效果，保证了复杂地质条件下隧道施工的安全。对类似条件下的隧道修建具有重要的指导作用和参考价值。

Abstract：The water gushing with collapse in process of Wushaoling highway tunnel crossing F4 fault fracture zone is introduced. Combining with geological conditions of F4 fault fracture zone and features of water gushing with collapse，according to the methods of geological survey，field measurement and theoretical analysis，the mechanism of water gushing with collapse and the reasons of initial support failure caused by water gushing and collapse are investigated，and the inner links of which with the surrounding rocks，underground water and geologic structure are analyzed. The water crushing collapse is a kind of the gravel inrush hazard caused by the crushed belts of fault. The support design and construction organization scheme for segments with water gushing and tunnel face are researched，and treatment measures are proposed. According to the measurement results，it is shown that the treatment measures can achieve satisfying results and can ensure the safety of tunnel construction under complicated geological conditions. This research could play an important guiding role and provides a significant reference value for tunnel construction under similar conditions.

Key words： tunnelling engineering Wushaoling tunnel fault fracture zone water gushing collapse
