摘要
在富水隧道施工过程中,常突发涌水、突泥等工程地质灾害,对施工安全危害极大。工程实践表明,单一的地质超前预报方法造成漏判、误判严重,难以确保隧道施工安全。文章结合铜锣山隧道工程地质条件,提出采用综合地质超前预报技术对铜锣山隧道施工涌水进行地质超前预报,充分发挥TRT法、瞬变电磁法和超前水平钻法技术的各自优势。工程应用效果表明,该种组合的综合地质超前预报技术为该隧道施工决策提供了有效的地质参考依据,在一定程度上避免了隧道涌水、突泥等地质灾害的发生。
Geological hazards like water inflow and mud bursts often occur during tunnel construction in water-rich geology, and these are detrimental to safe construction. Engineering practice indicates that single advance geological prediction may lead to erroneous judgment. Based on the geological conditions of the Tongluoshan tunnel, a comprehensive geological prediction technology was proposed concerning water bursts, namely, giving full play to the advantages of the TRT method, transient electromagnetic method, and advance horizontal drilling. The results show that this comprehensive technology provides an effective geological reference for construction decisions, to some extent preventing the tunnel from geological hazards.
