摘要
以沈阳地铁一号线为例,主要通过楔形环的设计,确定城市地铁盾构隧道在曲线上掘进时楔形环与标准环的配比,从而实现在各种曲线上管片环手动排版,可供施工人员参考。
Taking line 1 of Shengyang Metro as case history, the author presents the design of the wedged segment rings and the determination of the proportions of the wedged segment rings to the standard segment rings for curved sections of shield-driven Metro tunnels so that the array of the segment rings for various curved tunnel sections can be made artificially. The paper can provide reference for the relevant construction persons.
