摘要：
Site conditions of some strong earthquake stations in China are still unknown, which greatly restrict the effective application of strong earthquake records. A site classification scheme was proposed based on the strong earthquake data from Japanese KiK-net stations according to standard, and the mean site classification curves in China were calculated using the spectral ratio method from 279 stations of KiK-net. Then an empirical method for the site classification in China was proposed based on the range of predominant period, the peak value of spectral ratio and the spectral shape. Compared with the borehole information of stations in Sichuan province, China, the classified result shows that this method is independent of differences of regions. Finally, 113 strong earthquake stations of China were classified using the records during 2007 to 2011. ©, 2015, Academia Sinica. All right reserved.
