Navigation hubs built in plain area usually have large space span and compact structure layout. Safety monitoring performance, especially the surface deformation monitoring performance, is sensitive to the monitoring distance and structure features. Thus the monitoring system should be elaborately designed to meet the requirement of accuracy and robustness. Conventional approaches for surface deformation monitoring are time-consuming and suffering from low accuracy. In this paper, the designing strategies and monitoring techniques for surface deformation monitoring in Jiepai Navigation Hub, a typical navigation-power hub built in plain area, are demonstrated. The monitoring result shows that the designed monitoring system has good performance both in accuracy and robustness. The designing strategy can serve as a reference for other similar projects built in plain area. |
