徕卡GNSS在高层建筑施工测量中的应用

Application of Leica GNSS in Construction Measurement of Tall Building

高层建筑施工基准传递是施工测量的主要任务之一。结合工程实际施测过程,阐述了利用徕卡GNSS系统经典静态相对定位法实施基准传递的方法,并分析了GNSS测量基线精度,与常规方法测量数据进行了对比分析,最后进行了垂直度和标高控制的计算。实践表明,GNSS系统经典静态相对定位法可以满足高层建筑施工基准传递的需要。

Benchmark transfer in the construction of tall measurement. Combined with the engineering example, building is the main task of construction this paper elaborated the method about benchmark transfer by classical static relative positioning method of Leica GNSS system, and discussed to measurement, precision of GNSS measurement baseline, and compared and analyzed with the measurement data of the conventional method. At last, this paper calculated verticality and elevation control. The practice shows that classical static relative positioning method of GNSS system could meet the requirement of benchmark transfer in the construction of tall building.
