Abstract
Research to reliably predict the seismic response of nuclear power stations with a pile-raft foundation is needed to meet the high safety requirements of nuclear power stations. In this study, a scaled superstructure with a 4×3 pile-raft foundation, which is constructed in Shanxi kaolin clay, is modelled. Accordingly, the characteristics of seismic response for nuclear power stations with a pile-raft foundation are analyzed using dynamic centrifuge tests. In particular, multiple earthquake motions with different magnitudes and frequency properties are utilized to map the relationship between structural response and properties of earthquake motions. The results show that the seismic response of the soil, raft, and structure are significantly affected by the natural frequency and magnitude of the earthquake motion. The soil surface acceleration is lower than the raft acceleration. The results provide a reliable reference to better understand the seismic response of nuclear power stations.
