青岛海湾大桥变形监测方案及应用分析

在众多变形监测的方法中,GPS无疑是最有效的手段之一,特别是在像海湾大桥这样需要连续监测的建筑中。但是由于GPS成本过高,而限制其发展,本文中通过分析几种监测的方法,选择GPS多天线阵列变形监测系统能很好地解决这一问题。此系统拥有与常规GPS监测方法相当的精度,但是大大地降低了成本。可以应用于青岛海湾大桥的变形监测中。

Application and analysis on the deformation monitoring project of the Qingdao gulf bridge

In all kinds of deformation monitoring methods, GPS is proved to be one of the most effective tools, especially in some constructions which need continuously be monitored such as the gulf bridge. However, the high cost restricts the development of GPS. This paper analyses several methods of monitoring and the GPS multi-antenna array system was chosen to solve this problem commendably. This system has the same precision as the ordinary GPS monitoring methods but much lower cost which could certainly be used in the deformation monitoring of the Qingdao gulf bridge.
