However, the process of generating this complex response is not yet clarified. In this study, boundary element-perturbation method has been developed to investigate scattering of seismic waves due to an irregular surface. This method is based on the boundary element method in frequency domain and perturbation technique employing the Neumann series. By using this method, the ground response can be separated into those induced by incident waves and scattered waves. Numerical results showed that the amplitudes of the scattered waves are affected by both distance and direction of the irregular surface to the observation points.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人土木学会"}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.2208/jscej.2005.787_81","subitem_relation_type_select":"DOI"}}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18827187","subitem_source_identifier_type":"ISSN"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"MOGI, Hidenori"},{"subitem_text_value":"Kawakami, Hideji"},{"subitem_text_value":"FUKUHARA, Koji"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002680"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学工学部建設工学科"},{"subitem_text_value":"埼玉大学教授地圏科学研究センター"},{"subitem_text_value":"埼玉大学理工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"Geosphere Research Institute of Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2005-4"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"茂木, 秀則"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"川上, 英二"},{"creatorName":"カワカミ, ヒデジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"福原, 幸司"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002680.pdf","filesize":[{"value":"651.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002680.pdf","url":"https://sucra.repo.nii.ac.jp/record/14353/files/A1002680.pdf"},"version_id":"4f3416ee-909e-4f49-a447-3ffe0f8dbd91"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"boundary element-perturbation method","subitem_subject_scheme":"Other"},{"subitem_subject":"Neumann series","subitem_subject_scheme":"Other"},{"subitem_subject":"irregular topography","subitem_subject_scheme":"Other"},{"subitem_subject":"scattered wave","subitem_subject_scheme":"Other"},{"subitem_subject":"twodimensional","subitem_subject_scheme":"Other"},{"subitem_subject":"SH wavefield","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"境界要素法とノイマン級数に基づく摂動解法を組合せた起伏地形の地震応答解析手法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"境界要素法とノイマン級数に基づく摂動解法を組合せた起伏地形の地震応答解析手法"}]},"item_type_id":"119","owner":"3","path":["242"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-06-02"},"publish_date":"2008-06-02","publish_status":"0","recid":"14353","relation_version_is_last":true,"title":["境界要素法とノイマン級数に基づく摂動解法を組合せた起伏地形の地震応答解析手法"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:00:25.765976+00:00"}
