Deformation monitoring of super high-rise buildings based on BDS PPP

Deformation monitoring of Super high-rise buildings is an important part of the subsequent health assessment and safety assessment of super high-rise bulildings. At present, BDS Navigation Satellite System(BDS) has been widely used in building deformation monitoring. Based on BDS precise point positioning technology, this paper analyzes the deformation trend of three high-level monitoring points based on measurements of a super high-rise building in China. Results show that when the monitoring time reaches 1 h, the data starts to converge, the positioning accuracy can reach centimeter level, and the deformation trend of super high-rise buildings can be monitored, which provides a new technical means for future deformation monitoring of super high-rise buildings.
