 note = {本研究では震度増分を精度良く評価するための基礎的な情報を得ることを目的として，震源スペクトルやサイト増幅特性の震度増分への影響を調べた．まず，地震動スペクトルと地盤増幅度の関係式に基づき，震度増分の評価式を求めた．続いて，得られた評価式を用いて，3つの地震タイプ，様々なマグニチュード，高域遮断振動数，サイト増幅特性に対する震度増分を計算した．サイト増幅特性の1次ピーク振動数と震度増分の関係を調べた結果，3つの地震タイプともマグニチュードが大きくなるほど震度増分が最大となる振動数が低振動数側にシフトした．また，いずれの地震タイプでもマグニチュードの増大につれて震度増分が一定の値に収束する傾向が見られた．, In this study, we investigated the influence of site amplification effect and source spectra on amplification of seismic intensity for the purpose of obtaining basic information for accurately evaluating the amplification of seismic intensity (dI). Firstly, an evaluation formula for dI was obtained based on the relation between earthquake motion spectrum and amplification factor of earthquake motion index. Using the obtained evaluation formula, dI for three earthquake types, various magnitudes, fmax, site amplification effects was estimated. As a result of investigating the relationship between the fundamental peak frequency of site amplification effects and dI, the frequency of maximum dI was shifted to the lower frequency range as magnitude increased for all earthquake types. In all earthquake types, dI tended to converge to a certain value as magnitude increased., 金沢大学理工研究域地球社会基盤学系},
