摘　　要：洞内双导线是指在洞内布设主副两条导线,在盾构机尾部利用一公共点形成闭合导线,提高控制点的精度,进而实现施工质量的可控。通过济南R3线济南新东站–滩头站区间右线联系测量实例,论证了洞内双导线的可行性。Double conductors in tunnel mean that two conductors,i.e.main and auxiliary,are allocated in the tunnel.At the tail of shield machine,use one common point to form a closed conductor and improve the accuracy of control points,so as to control the construction quality.Discuss and demonstrate the feasibility of double conductors in tunnel,based on the connection survey of right line between New Jinandong Station and Tantou Station of Jinan Line R3.
