Abstract: Due to the operation characteristics of pumped storage power station, the water level changes frequently during the processes of power storage and generation, leaving the concrete face slab in a complex and changing environment for a long time, which is increasing the possibility of slab cracking and threatening the safe and stable operation of the power station. The technical route combining data review and on- site investigation is used to investigate and analyze the concrete face slab cracks of several pumped storage power stations. The main types and causes of cracks are summarized, and the corresponding treatment and prevention measures are put forward, which provides a reference for the application of concrete faced rockfill dams in pumped storage power stations in the future.

Key words: pumped storage power station, concrete face slab, crack
