"地震被害と地盤構造は密接に関係している。しかし地盤の動的物性値に関するデータは量的にも質的にも不足している。従って既往の地盤資料を有効活用するとともに、地震観測記録や微動測定記録などの観測データと相互補完することが重要となる。そこで本研究では、既存の地盤資料をデータベース化して有効活用する地盤モデリングGISを構築し、新たに実施した常時微動記録を融合させて、都市内の地盤構造を構築することを試みた。まず、既往の地盤資料を収集・データベース化し、問題をオブジェクト指向分析した上で、動的地盤モデル構築用の地理情報システム(GIS)を構築した。これにより、名古屋市内の任意の場所での地層断面図の推定、速度構造の推定、重複反射解析による地盤増幅特性の推定といった一連の動作をインタラクティブに行えるようにした。これと併せて、国土数値情報に基づく地盤増幅度の推定式も作成し、地盤データが不十分な地域での方策を検討した。さらに、名古屋市内の計三百数十カ所において常時微動実測を実施し、市内全域での地盤震動特性に関するデータベースを構築した。H/Vスペクトルの周期特性と名古屋市内の地盤構造に基づいて、地盤特性を7つのカテゴリーに分類した上で、微動の卓越周期と地盤モデリングGISにより推定された周期との相関を分析し、両者がおおむね対応していることを明らかにした。また、レーリー波の水平/上下のモード比のピーク周期とS波重複反射解析の卓越周期との相関を理論的に分析した上で、微動H/Vスペクトルの卓越周期から深部地盤の深度推定を試みた。本研究により、名古屋市の地震被害想定の精度が向上し、名古屋圏の適切な防災計画に結びつけることが可能となり、さらには、耐震基準の性能規定化後の地震荷重設定における地盤の増幅特性の適切な評価にも貢献できる。",
