Outline of Annual Research Achievements

研究項目1:揺れから揺れの予測法への広帯域地震波動伝播法則の導入
① 広帯域で適用可能なデータ同化手法の検討: 震度の予測を目的とした「揺れからの揺れの予測」では、データ同化手法が有効に機能した。これに②で得られる伝達関数との融合を図った。
② 広帯域地震動の伝達関数の検討: ①で得られる実況値から、伝達関数を掛ければ予測が可能となる。そこで、①のデータ同化手法との融合、また、研究項目2から得られる地盤増幅特性フィルターとの組み合わせをことを試みた。
研究項目2:地盤増幅特性フィルターへの時間遅れの導入
③ 周波数ごとの時間遅れの推定: ④から得られる設計手法に従い、各地点での増幅率と時間遅れを時間軸上でのフィルターで表現することを進めた。
④ 時間遅れをフィルターに導入する手法の検討: 有限個のハイパス、ローパスフィルターの組み合わせを用いて、広帯域での時間遅れを含んだ形での増幅特性をフィルターで再現することを行った。これらを論文で執筆することを進めている。
