摘　　要：根据涪秀二线新白沙沱隧道的施工,引入悬臂掘进机非爆开挖,不受营业线影响,可每天多循环进行开挖支护施工。Taking the construction of the new Baishatuo tunnel on the second line of Fuxiu as an example,this paper introduces the non-blasting excavation method of the boom-type roadheader,which is not affected by the running line,and can carry out excavation and support construction in multiple cycles every day.

关 键 词：邻近营业线 单线隧道 悬臂式掘进机 施工
