Research on Measurement of Tunnel Convergence

HUANG Mao-hua,XIE Yi-ling (Shang hai Surveying and Mapping Institute, Shanghai, 200063, China)  
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.
