Abstract

The hydro-electric power dam of Luzzone in Switzerland has been heightened by 17 m to 225 m. Distributed fiber optical sensors, based on wavelength multiplexed Bragg gratings, have been embedded in the concrete to monitor temperature and strain evolution. The sensors were designed to make them suitable for embedding and operation in this harsh environment. Data taken during curing and the first year afterwards are presented.
