摘要
宜兴抽水蓄能电站地下厂房结构关键部位的刚度满足厂家要求,通过厂房整体结构的模态分析,自振频率与机组的激振频率满足规范要求,另外,建立了宜兴工程厂房振动评估标准,并提出厂房结构的减振措施,从1号机现场试运行情况看,电站运行后厂房结构抗振性能良好。
The stiffness of key structures for underground powerhouse of Yixing pumped-storage power station meets the requirements of the Manufacturer. The key structure＇s self-vibration frequency and excitation vibration frequency are all accord with the specifications according to the integral structure model analysis of the powerhouse. The appraisal criterion of the powerhouse vibration for Yixing pumped-storage power station was set up and the damping measures for powerhouse structure was suggested. The anti-vibration performance of the powerhouse structure is good after the station was put into operation.
