隧道收敛测量方法研究

隧道工程在建设的过程中以及竣工后均需要对其进行收敛测量，以监测断面在水平和竖直方向的位移，确保隧道的正常运营。本文介绍了三种常用的伺服全站仪，以及如何进行扫描及相关的数据处理，根据最小二乘，推导出了求解隧道圆心坐标和半径的公式，最后介绍了一个实际的扫描实例。

Research on Measurement of Tunnel Convergence

To ensure the normal operation of the tunnel, it needs to be convergence measured to monitor displacement on the level and vertical direction in the course of construction and after completion. This article describes three types of commonly used Servo Total Station, as well as how to proceed with scanning and related data processing, based on least squares method, the solution derived from the tunnel center coordinates and radius of the formula and finally introduced a practical example of the scan.
