一、序言对核电站的抗震设计来说,估计未来地震的强地面运动是必不可少的。因此,根据强震观测资料制定了若干设计谱。这些谱的一个典型例子是由Hisada等人提出的,是在岩石场地上得到的与震级、震中距有关的强震设计谱。在日本这些谱已实际应用于核电站 I. Preface For seismic design of nuclear power plants, it is essential to estimate the strong ground motion of future earthquakes. Therefore, based on strong earthquake observation data to develop a number of design spectrum. A typical example of these spectra is proposed by Hisada et al., Which is a strong earthquake design spectrum associated with magnitude and epicentral distances on rocky sites. These spectra have actually been applied to nuclear power plants in Japan
