摘要：

The Jalon viaduct is a six-span box girder railway bridge for high-speed trains at Calatayud, Spain. An extensive vibration measurement campaign was performed in order to design a permanent vibration monitoring system. Natural frequencies, damping ratios and mode shapes are extracted from the measured vibration data. Both the ambient vibration data and the free vibration data obtained directly after the passage of a high-speed train provide the results with good accuracy. The bridge dynamics are investigated through the tuning of a finite element model based on the experimental modal data.
