Abstract

GPS can now be used for the real time monitoring of large scale structures, such as reservoirs, tall buildings and bridges. The paper describes the way in which the Humber Bridge on Humberside and the Clifton Bridge in Nottingham were monitored using kinematic GPS. The results show remarkable accuracies of the order of a few millimetres in all three coordinate components. They demonstrate that the technique allows the collection of real time deflection data, which could be used to determine the deformation characteristics of the bridge and eventually provide a real time 'structural failure alarm' capability.
