摘要
文章以宜万线野三关隧道"602"溶腔为例,对深埋大型富水溶腔隧道的综合施工技术进行了系统的论述,主要包括查找溶腔、判释溶腔、锁定溶腔、打开溶腔、处治溶腔等释能降压技术,以及泄水洞、信息化注浆、开挖支护、长期监测、结构安全评价等过溶腔安全施工关键技术。
Taking the ＂602＂ karst cavity encountered in the construction of Yeshanguan tunnel on Yichang-Wanzhou railway for example,the paper systematically describes the comprehensive construction techniques of deep tunnels passing through large karst cavity with rich water,namely the energy releasing and pressure reduction techniques including locating,identifying,locking,disclosing and treating karst cavities,as well as safety construction techniques for passing through cavities including discharge adits excavation,information-oriented grouting,supporting,long-term monitoring and safety evaluation.
