摘要
地铁盾构贯通测量中的横向贯通误差精度的控制是地铁施工测量中的难点,以某市地铁1号线一期工程某区间为例,通过对贯通测量误差分配、横向贯通精度影响值估算的分析与研究,总结了对于不同长度地铁隧道盾构工程的贯通测量实施方案,并提出了一些建议。
The control of lateral breakthrough error is a difficult problem in metro construction survey. Taking a section in the Metro Line #1＇s first phase project of a certain city for an example,error distribution and accuracy estimation of breakthrough survey was analyzed,and then different implementing schemes in various lengths of metro tunnel shield projects summarized. Some suggestions on metro shield tunnels breakthrough survey were finally proposed,providing technical and practical experience for the further metro construction survey as reference.
