Automatic Monitoring System for Continuous Structural
On this article, the installation and operation in two different sites of an automatic system for continuous monitoring of tunnels based on Fiber Bragg Grating (FBG) technology is presented. The first example of application of the SysTunnel refers to the Rossio Tunnel in Lisbon. The system has been successfully operating since its installation in 2008 after the rehabilitation of the tunnel. The experience on the long term remote interface usage is shared. In a different approach the SysTunnel system was also installed at Metrô de São Paulo for a limited period of almost a year to control the structure’s behavior during a neighbor construction. At the end a new SysTunnel application yet to be implemented in a new tunnel in Caracas is explained.
