"OFSTUNN' Optical fiber Sensors For Remote Tunnel Displacement Monitoring

Dates:
2001-2004

Sponsors:
UK DTI/EPSRC LINK OSDA Program

Project Brief:
To develop a remote system of tunnel settlement, rotation and distortion monitoring using fiber optic sensors for periodic examination by maintenance contractors as well as providing continuous monitoring during adjacent construction operations

Partners:
Smart Fibres
Sol Data
University of Birmingham
London Underground

Delivered:
- Development of a new sensor type - SmartRod

- Development of a fibreoptic displacement monitoring system based on SmartRod suited to tunnel settlement, rotation and distortion monitoring, and other civil engineering and geotechnical applications

- Live field trials of the developed system in a working road tunnel (see project reference)
