Abstract: The meteorological and geological conditions of Yalong river are complex. There is a series of challenges in safety and risk management of cascade hydropower projects. This paper summarizes the key technologies of safety management such as deeply embedded, long and large tunnel, underground powerhouse cavern groups, high slope and landslide mass, joint regulation and operation of cascade reservoirs etc. Using information technology of GNSS, unmanned aerial vehicle, BIM, GIS and so on, the real time safety monitoring system for flood discharge, earthquake monitoring technical system for cascade reservoirs, dam safety information management system and whole life cycle digital hydropower management platform are developed. The risk management and control with classification and emergency management command center are established. By comprehensive utilization of modern engineering and information technology, the engineering safety and risk stay in a controllable state.
