摘要
以齐岳山隧道F11断层区域横通道进正洞施工为例,介绍了超前帷幕注浆施工技术在复杂地质条件下的应用,阐述了大断层区域内超前帷幕注浆技术的注浆设计、钻探注浆情况分析、注浆效果评定、开挖揭示对比,为断层破碎带、软弱围岩施工提供了一定的经验借鉴。
Taking the construction of the main tunnel through cross entryway within F11 fault area of Qiyueshan Tunnel as an example,this paper introduces the application of advanced curtain grouting construction technology under complex geological conditions,expounds the grouting design,drilling/grouting situation analysis,grouting effect evaluation and excavation reveal/contrast of advanced curtain grouting construction technology adopted in large fault areas,which provide some experiences and references for the construction of fault fracture zone and weak surrounding rock.
