TORBELLA BRIDGE - HIGHWAY A/7 GENOA-SERRAVALLE

Monitoring the Torbella bridge

Client: Autostrade per l’Italia

 

The "OF" System is being installed on Torbella bridge to monitor the stress conditions, the deformations and the bridge vertical displacement, when vehicles pass over it.

 

It is planned to install about one hundred and fifty sensors, distributed on the bridge spans on each span beam.

 

The measures are carried out by all sensor at the same time, with a frequency of five hundred data per second, and transmitted through 1 km of optical fiber. More than seventy thousand data per second are acquired by 24/24h operating system.

 

Thermal strain sensors have been installed and connected to one acquisition machine on which runs the “OF” Software for the analysis, in real-time, of the parameters to be monitored.

 

The system will be operational by the end of January 2017.
