摘　　要：在大型发电站中,汽轮发电机基础是至关重要的部位,在地震中一旦产生破坏将会遭受重大损失。因此,对发电机基础抗震性的研究成了重中之重。本文结合工程实例对汽轮机基础的抗震性能进行试验研究,按1:10的缩尺比例制作发电机基础模型进行等比例试验,采用拟动力和拟静力相结合的方法对其进行综合分析,本次试验模拟了基础结构在6度多遇、6度罕遇以及7度罕遇三种地震波下的抗震性能,结果表明该基础结构的各项抗震性能指标均满足规范要求,在上述两种地震作用下该基础结构安全。In a large power station,the foundation of a turbo-generator is a vital part,and once it is damaged in an earthquake,it will suffer significant losses.Therefore,research on the seismic resistance of the generator foundation has become a top priority.Combining engineering examples,the seismic performance of the steam turbine foundation is test in this article,a basic model of the generator is made at a scale of 1:10,and the proportional test is conducted.A combination of pseudo-dynamic and pseudo-static methods is used to comprehensively analyze the seismic performance.The second test simulated the seismic performance of the foundation structure under three seismic waves:6-degree frequent encounter,6-degree rare encounter,and 7-degree rare encounter.The results show that the seismic performance indicators of the base structure meet the requirements of the specification.The infrastructure is safe under the influence.
