After the detection of a perpendicular fault to a railway and to avoid any risk that a train circulates on a collapsed area, the French railway service decided to reinforce the structure by geosynthetics that was considered as the best solution to avoid a long interruption of the traffic. Additionally, it was decided to install a new warning system called 'Geodetect', which combines reinforcement and strain measurement, in order to check his behaviour on real site condition. Particularly, the resistance during installation and the level of strain measured during the traffic were the main parameters to be followed. Considering the geometry of the structure and the various loads, the reinforcement part of the geosynthetic was designed to allow the respect the surface settlement criterions. The optical sensors network was designed to optimize the number of sensors and to ensure the detection by a minimum of one sensor. To not disturb the traffic of the trains in the daytime, geosynthetic was laid during the night.
