| 摘 要： | 由于隧道洞门存在测量放样和洞门安装施工误差,洞门施工完成后的实际中心坐标与洞门圈设计中心坐标存在偏差,需要实际测量确定盾构洞门中心坐标。本文研究利用全站仪免棱镜测距的新技术,开发盾构隧道洞门中心坐标检测的测量程序,提高检测工作效率。

Design of Tunnel Section Center Coordinates Acquiring Program Using Reflectorless Total Station |
| |
| Abstract: | During the tunnel construction process, two kinds of errors exist, one is the setting out error and the other one is the con-struction installation error.Due to these errors, the actual centers of the tunnel sections will be biased from the designed center coordi-nates.The acutal centers of the tunnel sections can be determined by the field surveying.This paper takes use of the data acquired from the reflectorless total station, and developed a program to compute the tunnel section centers using the least square adjustment, which is efficient in the real work. |
