Making Good Use of Suspension Bridge Health Monitoring System

摘要

In order to make good use of large-span suspension bridge health monitoring system, the design for Wuhan Yangluo Yangtze River Bridge health monitoring system(YLBHMS) is outlined, and the implementation of the deformation and vibration on-line monitoring system is introduced. Analysis of the measured temperature, the vertical deformation effect of the main cable and the girder, the longitudinal deformation effect of the main tower and the girder, The fingerprint files are accumulated for the assessment of temperature deformation, the work state of bearing and expansion joints in the follow-up operation;;The vibration system recorded the Wenchuan earthquake response, the analysis of the bridge vibration response concluded that the bridge seismic response is in the design scope, the work state of the bridge did not change after the earthquake.
