摘要
文中通过结合金花隧道工程实例,针对其出现的特大涌水现象,分析其主要原因并结合具体工程实际情况,提出切实可行的止水方案。通过施工现场验证,该种超前支护同时围岩加固-注浆止水相结合的综合治理方法,能有效解决恶劣地质条件下隧道大量涌水的问题,为同类工程提供参考和借鉴。
Based on the Jinhua tunnel project example, this article analyzes the main causes of the phenomenon and the main causes of the phenomenon and combines the actual conditions of the specific project to propose a feasible water stopping program. Through the verification of the construction site, this comprehensive support method for the combination of surrounding rock reinforcement and grouting and water shut-off for advanced support can effectively solve the problem of massive water inrush in tunnels under severe geological conditions, and provides reference and reference for similar projects.
