The dynamic matching design of shaft-foundation system is becoming more and more important for large-scale nuclear power units. In this paper, the present situation of shaft configuration and foundation matching in china was summarized, including different unit types, capacities and rated working speeds. Taking the spring isolated foundation and conventional foundation for 1000MW level as prototypes, two test rigs were separately built to study their dynamic characteristics. The analysis results can provide technical basis for large-scale nuclear power plant shaft-foundation matching design
