Experiment and Result for Measuring Dynamic Characteristics of Large Bridge Using GPS

  • This paper proceedes the actual test work for GPS dynamic monitoring, and introduces the experimental implementing scheme, data processing method and monitoring result.This paper availably obtains the vibration characteristics in the middle span of cable-stayed bridge by using the spectral analytic approach.The result and the surveying value obtained by the accelerometer when the bridge was completed are very identical.The results have shown that, with GPS receiver of the high sampling rate and suitable data processing method, the vibration characteristics of the bridge structure can be determined with high accuracy.
