Abstract
The Grand Paris Express (GPE) is a new metro project for the Paris region. Construction work began mid-June 2016 and is expected to last until 2030. Being located in a high-density urbanization context with poor soil strength conditions, the project is driven by risk management and neighborhood disturbance minimization. Thus, structural and geotechnical monitoring is considered as critical for contractors and existing asset owners, with a large scope of work dealing with existing and new construction. As the number of sensors and data collected is very high, innovative monitoring technologies have been developed and are currently being deployed: LoRa wireless radio frequency data loggers, long range optical fiber strain sensing, geodetic network for multiple total stations, correlated data from geodetic, InSAR (Interferometric Synthetic Aperture Radar) and conventional sensors (vibrating wire, MEMS, electronic sensors) and large data servers with real time displays and alarms.
