摘要: 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 embedded the concrete monitor temperature and strain evolution. sensors were designed make them suitable for embedding operation this harsh environment. Data taken during curing first year afterwards are presented.
