摘　　要：汽轮发电机组的抗震设计是火电厂建设的重要部分。本文针对火电厂中汽轮发电机组刚性基础和弹簧基础进行抗震性能分析,研究讨论两种不同类型基础的抗震性能,结果表明,刚性基础适用于设防烈度不超过7度的区域,岛式弹簧基础适用于设防烈度8度区的高烈度区,研究结果可为高烈度地震区火电厂汽轮发电机组抗震策略提供参考借鉴。Seismic design of steam turbine generator set is an important part of thermal power plant construction.This paper analyzes the seismic performance of the rigid foundation and the spring foundation of the steam turbine generator set in the thermal power plant,and discusses the seismic performance of the two different types of foundations.The results show that the rigid foundation is suitable for the area with less than 7 degrees of fortification intensity,the island spring foundation is suitable for the high-intensity area with less than 8 degrees of fortification intensity,and the combined structural spring foundation is suitable for the area with more than 8 degrees of strong earthquake.The research results can provide reference for the seismic strategy of steam turbine generator units of thermal power plants in high intensity earthquake area.
