摘要
通过乌坑坝隧道北京端左线冲沟地段的施工实例,介绍渗水软弱围岩浅埋偏压隧道地表双液注浆锚管加固的施工方法,并对加固效果及其优缺点进行分析.
On the basis of a construction sample case of a valley section at left entrance of Wukengba tunnel, this arti-cle introduces the strengthening method of ground surface dual liquid anchor pipe grouting in permeable soft surround-ing rock tunnel with shallow cover and lateral pressure, and analyzes the effectiveness of the strengthening and its strong and weak points as well.
