The construction distance of the singletube doubledeck rivercrossing shield tunnel on Weisan Road in Nanjing is long; the construction space is limited; and the construction schedule is tight. As a result, the precasting technologies for the internal structure of the tunnel are studied; and then the beamdeckcolumn structure system by means of castinsitu and precast and rational construction procedure are adopted. Finally, the rational construction scheme of singletube doubledeck extralong shield tunnel is adopted. The construction practice shows that the technologies used can improve the construction efficiency greatly, shorten the construction schedule and reduce the cost.
