摘要
结合广州地铁三号线[天～华]两个区问段隧道施工测量工作的实践,简述地铁盾构隧道施工中的各种测量工作,重点分析导线测量精度对隧道贯通精度的影响,以及如何采取适当的技术方法来提高测量精度。
On basis of the survey practice in Tian-Hua shield-bored running tunnel on line 3 of Guangzhou author presents the survey works in the construction of the shield-bored Metro tunnels, analyzes on the influ traverse survey accuracy on the holing-through accuracy and recommends some countermeasures to improve through accuracy.
