| 内容記述 | In this study we first try to separate so-called source spectra, attenuation coeffcient, and site amplification factors from K-Net, KiK-net, and JMA strong-motion (Shindo-kei) network records observed throughout Japan. As a reference site, we use one rock station of KiK-net, and we remove a very small site effect caused by weathered layers from the record using 1-D theoretical amplification. Once we obtain site amplification factors, we try to obtain nonlinear site factors for high PGA records observed during the 2003 Tokachi-Oki earthquake as a ratio of the observed record with respect to the hypothesized input bedrock motion calculated as an average from small PGA (i.e., less than 200 Gals) records. When we compare these site effects with linear site effects for smaller PGA records, we find that several sites show lower peak amplitude with lower peak frequency than expected from previous studies. However, at a few very soft sites we found higher peak amplitude with lower peak frequency. This phenomenon can be interpreted to occur as the impedance effect (makes amplitude higher) is strengthened by nonlinearity, and overcomes the damping effect (makes amplitude lower). | |||||
