Azimuth-Dependent Site Amplification
本研究使用SMART-1強震儀陣列中的兩個測站所收錄的地震記錄探討場址放大效應隨震央方位的變化情形。本文共選用了十五個地震，乃因它們同時啓動E01土層測站和E02岩盤測站的強震儀。首先，我們將E01和E02的記錄分別截取一段包含直接S波的波線，並求其傅氏振幅譜，然後再求E01對E02之頻譜比。由於岩盤測站受場址效應的影響較小，因此頻譜比可將大部份的震源及波傳路徑效應消除，而呈現E01的場址放大效應。 為了比較不同震央距及方位角對放大效應的影響，我們將這些地震分成十組，使同一組之地震具有相近的震央距及反方位角，分析這些地震之結果顯示：不同組資料有不同之放大效應，而各組間並無明顯的系統性差異。至於...

為了比較不同震央距及方位角對放大效應的影響，我們將這些地震分成十組，使同一組之地震具有相近的震央距及反方位角，分析這些地震之結果顯示：不同組資料有不同之放大效應，而各組間並無明顯的系統性差異。至於同一組的地震，預期應有相似的頻譜比，但所得的結果卻只有部份組之部份頻段存在相似性，而這些異常現象可歸因於近震源及非線性放大兩種效應所致。 |
