The seismic risk monitoring system of Kezier Reservoir was built on the bases of strong shock net,F2 active fault monitoring equipment,center of observation and analysis,and anti-seismic center.These installations were functioned by fault compendium established on GIS platform,potential epicenter,peak value acceleration area,dam location,seismic information transmit system,and digital dam disaster reduction system.The strong seismic monitoring information system was applied to anti-seismic risk decision support and operation management to realize on-line treatment of the process curve of seismic acceleration transmitted from sub-stations and to analyze the maximum acceleration values from various monitoring locations,dynamic magnified modulus,salience frequency,structural self-shake frequency,sustained seismic period,and the judgment of earthquake induced at reservoir.All these would provide reliable rapid support for various decisions making.In this way the first rapid seismic alerting system and primary digital disaster reduction system were built on the dam of Kezier reservoir located on active fault,from which rapid effective repair measures after earthquake were formed and research basis for constructing dam on active fault were provided.
