| 摘 要： | 超高层建筑施工中常采用激光投点仪向上传递地面控制点作为测量基准。为了避免投点误差过大,本文采用BDS+GPS技术进行组网监测其投点精度,给出了超高层建筑BDS+GPS监测相应的数据处理策略,对比分析了BDS、GPS及组合BDS+GPS 3系统之间,以及与激光投点前地面点坐标之间的差异。结果表明,GPS和BDS+GPS组合系统定位精度相当,BDS定位性能稍差,但满足超高层监测精度要求,利用北斗技术进行超高层建筑基准传递工作具有一定可行性。

| Abstract: | In the monitoring of super high-rise buildings, the ground control points are used to upward transfer as the measuring datum by laser shots.In order to avoid the excessive errors of the casting points, the BDS+GPS technology is adopted to monitor the points’ accuracy.This paper gives the corresponding strategies of data processing in high-rise building monitoring using BDS+GPS technology, with the comparative analysis of the difference among the BDS, GPS, combined BDS+GPS system and the ground point coordinates, which indicate that GPS and combined BDS+GPS have approximate accuracy, and BDS positioning performance is slightly worse.The BDS technology can meet the super high monitoring accuracy requirements, and super high-rise building datum transfer work has a certain feasibility of using BDS technology. |
