摘　　要：红石水电站机组振动严重,并诱发大坝振动。通过现场测试分析和大坝三维有限元计算,基本摸清了诱发大坝振动的主要振源、共振的机理和振动传递放大过程;采取补气等措施,有效地消减了振动,从而减轻了对大坝安全的影响。The units in Hongshi Hydropower Station have been vibrating badly and induced dam vibrating.In this paper the author basi-cally makes the aspects that induced dam vibrating clear of main vibrating,resonance mechanism and the process of vibrating,transferring and amplifying.Some steps are taken so effectively reduced dam vibrating,consequently lessened the influence on dam safety.
