摘要
以广州珠江黄埔大桥索塔为对象,采用高精度测绘仪器,以传统大地控制网和卫星大地控制网相结合的布网方式,对主桥的三个索塔进行水平位移和垂直位移监测。通过两种作业方法相融合,既可以相互检核,也可以弥补单种作业方法的不足和局限性。
Taking the pylon towers of Huangpu Bridge of Pearl River as the object of study, usehigh precision surveying instrument to monitor the horizontal and vertical displacement of the3 pylon towers through traditional geodetic network and GPS satellite geodetic control network.Being combined with the two different surveying methods, Not only the measurement results could be mutually checked, but also the insufficiency and limitation of one surveying methodcouldbe compensated, which has an important practical significance to ensure the safety of Huangpu Bridge.
