摘要
可逆式水泵水轮机组具有水头高、容量大、双向运行、转速高及多采用地下厂房等显著特点，许多关键问题需专门研究，振动问题即是其中之一．笔者对抽水蓄能电站机组混凝土支承结构在各种动力荷载作用下的振动响应进行了分析；利用三维空间有限无法建立计算模型；并结合某大型电站对结构动力响应及动应力状态作了探讨．
The dynamic response of concrete supporting structure of pump storage units under un-balance dynamic load were analysised with 3-0 space finite element method. The dynamic deflections and stresses of a calculating example were given. Some vibration characteristics of the supporting structure were concluded.
