摘要
以国家重点工程——虎门大桥为依托，根据工程施工变形的特点，试验适当的采样速度、监测时段和测量模式进行悬索桥架缆和钢箱梁吊装ＧＰＳ塔顶变形监测。监测结果满足施工监测的精度要求。
Humen bridge is a national major engineering project.To meet its
special construction in cable and stiffening girder erection of such suspension structure,the top
deformation of main tower is monitored by GPS with testing sampling rate,time window and modes
of operation.Practical example has verfied that GPS “rapid static” and “stop and go” survey
can meet the precision needs of monitoring.
