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

在超高层建筑建造过程中,常用测量机器人监测中间楼层的监测点的变形。削弱建筑晃动影响对于监测结果的稳定性至关重要。为此,首先提出一种利用楼顶卫星接收机测量建筑晃动情况,通过内插得到中间楼层瞬时晃动影响的方法,并通过实验验证该方法的有效性。在此基础上,利用该方法对多期监测数据进行处理,结果表明该方法可获得更加稳定的监测结果。将处理结果与有限元分析的结果进行比较,结果表明使用该方法后监测结果与有限元分析的结果吻合度较高。

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.
