摘　　要：水电站厂房在水轮机机组运行状态下,会受到水轮机机组通过轴系统及其支撑结构传递到厂房的激振力,导致厂房结构产生振动,严重时会使结构损坏。对黑龙江荒沟抽水蓄能电站地下厂房3#机组段进行动力特性分析,结果表明:当前的设计满足机墩结构的刚度要求,厂房结构关键部位在机组动荷载作用下的动位移和动应力也均满足规范要求,厂房结构设计合理。结果可对此类研究提供参考。Under the operating condition of the turbine unit, the hydropower station will be excited by the turbine unit through the shaft system and its supporting structure to the plant, causing vibration of the plant structure and serious structural damage. The dynamic characteristics of the 3# unit section of the underground powerhouse of the Heilongjiang Wastewater Pumped Storage Power Station are analyzed. The results show that the current design satisfies the stiffness requirements of the pier structure, and the dynamic displacement and dynamic stress of the key parts of the plant structure under the dynamic load of the unit are also All meet the requirements of the specification, and the structure of the plant is reasonable. The results can provide a reference for such research.
