Monitoring of Horizontal Displacement of a Super-Tall Structure During Construction Based on Navigation Satellite and Robotic Total Station

Abstract:

In the construction of a super-tall structure， robotic total station （RTS） is more suitable for monitoring the deformation of points in the middle floors. Reducing the impact of building shaking is critical to the stability of monitoring results. This paper introduces a method of using roof navigation satellite receiver to monitor the vibration of the roof， and then interpolates roof results to get the impact of instantaneous shaking of middle floors， thus eliminating the impact of building shaking on RTS monitoring results. Then， the effectiveness of this method is verified by experiments. Multi-phase monitoring data are processed by using this method. The results show that this method can obtain more stable monitoring results. A comparison of the results of measurement with those of finite element analysis shows that the monitoring results is more consistent with the finite element analysis results.
