隧道超前地质预报方法针对性选定及组合应用研究

Research on Targeted Selection Method of Advanced Geological Forecast in Tunnel and Its Combined Application

随着我国近年来基础设施建设的飞速发展,铁路、公路、水电、核电隧道埋深及长度越来越大,地质条件越来越复杂,大量的工程实践表明,隧道施工过程中随时面临着突发地质变化的影响。隧道超前地质预报是保证隧道施工安全的重要环节和重要技术手段,但是面临多种多样的隧道超前地质预报方法,如何能有针对性选定方法,并且进行合理化组合可发挥高效作用是现阶段研究重点,本文通过成兰铁路极高风险的跃龙门隧道超前地质预报工作对针对性选定方法和组合应用进行阐述和分析研究,可为今后隧道施工在超前地质预报工作中提供有益借鉴。

In recent years, with the rapid development of China＇s infrastructure construction, the buried depth and length of railway, highway, hydropower and nuclear power tunnel become more and more longer, and the geological conditions are more complex. A large number of engineering practices show that sudden geological changes would be caused at any time in the process of tunnel construction. Tunnel geological prediction is an important link and technical means to ensure the safety of tunnel construction. However, faced with various kinds of tunnel geological prediction methods, how to be able to have a targeted approach and carry on a proper combination to play an effective role are current research focuses. This paper expounded and researched on the targeted selection method and its combined application based on the high-risk Yuelongmen Tunnel geological prediction in Chengdu-Lanzhou Railway, which could provide a useful reference for advanced geological forecast in future tunnel construction.
