| 内容記述 | The central city in Kashiwazaki suffered severe building damage by the 2007 Niigata-ken Chuetsu-oki Earthquake. This study has examined amplification of seismic motion in surface layer at this area by earthquake response analysis. Seismic response analysis was performed by using the estimated outcrop waves of the alluvial basement layer (Nishiyama Formation) and the analysis model of surface layer at K-net Kashiwazaki located in the central area of Kashiwazaki. Amplification of seismic motion at surface layer was estimated by using the amplification rate of ground surface to the bottom of surface layer. For relatively weak seismic motion (the 2007 Noto-Hanto Earthquake), the amplification rate of about 2 to 3 in the primary predominant period(1-1.5s) and about 3 to 4 in the secondary predominant period(around 0.4s) were estimated. this primary predominant period is consistent with the amplified period estimated by microtremor measurement. For strong seismic motion (the 2007 Niigataken Chuetsu-oki Earthquake), the amplification rate was estimated about 2 to 3 in the primary predominant period, The primary predominant period was 1.5 to 2 times longer than the above value due to the influence of non-linearity of the ground soil. Amplification in the secondary predominant period was almost not observed from the response of this earthquake motion. |
