| 中文摘要:TBM开挖隧洞，由于刀盘及刀具的限制，目前开挖完的隧洞为同一直径，为了保证后期衬砌施工中结构的强度，需要对不同的围岩类别采取不同的衬砌厚度。研究表明，采取可变径全圆针梁台车进行这方面的衬砌，具有明显的优越性。本文基于吉林引松供水工程项目，论述了可变径全圆针梁台车在TBM施工隧洞衬砌中的应用。 |

| Abstract:The TBM excavation tunnel, due to the limitation of the boring head and the cutter, the tunnels currently excavated are of the same diameter. In order to ensure the strength of the structure in the later lining construction, it is necessary to adopt different lining thicknesses to different surrounding rock types. Our research indicates that take variable diameter full circle needle beam formwork trolley has obvious advantages in this aspect of lining. Based on the Songhua River water supply project in central Jilin cities, this paper discusses the application of variable diameter full circle needle beam formwork trolley in the TBM construction tunnel lining. |
