摘　　要：由于核电单机容量越来越大,受到材料性能限制,半转速式汽轮发电机组已开始广泛地使用。为解决频率降低带来的抗振动问题,汽轮机基础结构发生了较大变化,多数采用弹簧隔振器来改变基础台板固有频率,避开共振区。对福清核电1~#、2~#机组工程常规岛中的汽轮发电机组弹簧隔振基础的振动特性进行模型试验及原型实测,验证计算理论。Limited by material pro perties, half speed type turbo generator unit is widely used due to much and much bigger nuclear power capacity. Steam turbine foundation structure happened great changes in order to solve vibration resistance problems caused by decreased frequency. Spring vibration isolator was used mostly to change inherent frequency of foundation sole plate,and avoid the resonance region. Vibration characteristics model experiment of vibration isolating spring supported foundation of steam turbine generator unit used in conventional island of 1~#、2~#in Fuqing Nuclear Power was carried out and prototype test was made, and numerical theory was verified in this paper.
