中文摘要：

以武汉长江二桥GPS动态监测试验为例，利用TGO软件对监测结果进行了处理，通过傅立叶变换得到了跨中振动特征，验证了动态GPS技术监测大型桥梁振动特性的可行性。本次试验采用了具有10Hz高采样率的GPS接收机和配套的数据处理方法，实现了高精度大型桥梁振动特性的确定。

英文摘要：

Through a GPS dynamic monitoring experiment on the No. 2 bridge of Yangtze River in Wuhan, the vibration characteristics in the middle span is obtained by utilizing TGO software and the Fourier transform. The result proves that GPS is capable of monitoring vibration characteristics of large bridge. The high 10 Hz sampling rate of GPS receivers and supporting data processing methods are used to obtain and identify a high precision vibration characteristics of the large bridge.
