【 摘 要 】

Vibration of the powerhouse has an important influence on safe operation of hydropower station and health of operation personnel. In the present paper, intense vibration of local structures of Zhanghewan pumped-storage powerhouse is studied, and the reason of intense vibration is illustrated through analyzing the main excitation sources and the natural frequencies of local structures. The revelation from the research process and conclusions is that the entirety resonance of the powerhouse should be avoided absolutely during the process of design, and the resonance between local structures and the main excitation sources should be avoided as well.
