高速公路大断面黄土隧道关键工序机械化配套研究

Research on Key Process Mechanization Matching of Large Section Loess Tunnel of Expressway

为实现高速公路大断面黄土隧道机械化配套施工,文中以定临高速公路黑庄坪隧道工程为依托,通过对影响大断面黄土隧道开挖、初支关键工序的机械化配套存在的问题进行研究,提出超前支护、超欠挖控制关键技术措施,并在黑庄坪隧道得到成功应用。

To realize the mechanization construction of large section loess tunnel of expressway,based on the set of Heizhuangping tunnel project in Dinglin highway,the problems existing in the mechanization matching of key procedures which will affect the excavation and initial support of large section loess tunnel are discussed.At the same time,the key technical measures of advanced support and overbreak control measures are discussed,and the research results are successfully applied in Heizhuangping tunnel.
