| Abstract: | Automatic deformation monitoring is used in many subway tunnels. Obtaining the actual monitoring result is based on the accurate coordinates of work base points. And stable reference points play important roles to get accurate coordinates. This paper illustrates the importance of the stable reference points to the deformation monitoring and the usage of the combination of posterior variances text in stability analysis. A stability test of horizontal datum network in a subway tunnel in Nanjin is done to verify the practicability of the combination of posterior variances. Through this analysis, the moving points are found. This analysis has certain reference significance for practical engineering monitoring. |
