摘要
以沪昆客专铁路丫口寨隧道穿村庄及河流浅埋段施工段为背景,对施工重难点进行了分析;通过方案对比详细介绍了单臂掘进机配合液压冲击锤隧道开挖法施工技术,在下穿地表建筑物、明河施工中的应用,对今后类似隧道工程施工提供了借鉴。
Taking the Yakouzhai Tunnel on Shanghai-Kunming High-speed Railway driving under the village and river shallow-buried section as a background,this paper carried out an analysis of the key and difficult points of construction. Compared with different schemes,the paper gave depth discussions on the construction technology of tunnel excavating method combined single cantilever heading machine with hydraulic percussion hammer,as well as the application in crossing the surface building and running river,which could provide reference for the construction of similar engineering in the future.
