Magnitude 6.8 was estimated at its epicenter north away from the shore of the district. A strong shock of earthquake, 6.0 to 6.4 of the intensity scale, attacked Kasiwazaki city, Nagaoka city and Kariwamura, Niigata, and IItsuna-machi, Nagano, and caused terrible disaster of social and industry infrastructures including domestic houses and agricultural facilities. In Kariwamura, sewerage facilities as well as the domestic houses were severely damaged by the liquefaction of the foundation soil. Kariwamura has experienced another huge earthquake, the Niigataken Chuetsu Earthquake in 2004. A large length of pipeline for rural sewerage was damaged by the soil liquefaction during this earthquake, but repaired successfully by using the sand soil mixed with lime admixture. These pipelines damaged in 2004 and repaired by soil improvement could eliminate safely the terrible damage of soil liquefaction caused by the Niigataken Chuetsu-oki Earthquake in 2007. This means that robust alternative of the soil improvement is effectively examined by the two big earthquakes in the Chuetsu district, Niigata. Firstly the terrible disaster caused by the Niigataken Chuetsu-oki Earthquake in 2007 is outlined in the paper. Then the damage of the sewerage pipelines studied in Kariwamura is summarized together with some results of laboratory soil test. The liquefaction resistance of soil is also calculated based on the field soil investigation. Lastly effectiveness and robustness of the alternative of the soil improvement against the soil liquefaction selected by Kariwamura are emphasized.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"163445","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Toshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"163446","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishino, Nobuyuki"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学農学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183393","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03858634","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森井, 俊広"}],"nameIdentifiers":[{"nameIdentifier":"163443","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西野, 信之"}],"nameIdentifiers":[{"nameIdentifier":"163444","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-20"}],"displaytype":"detail","filename":"147-153.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"147-153.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28411/files/147-153.pdf"},"version_id":"13095c12-cc49-4ced-b05a-05823a27c7b1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"2007年新潟県中越沖地震","subitem_subject_scheme":"Other"},{"subitem_subject":"農業集落排水処理施設","subitem_subject_scheme":"Other"},{"subitem_subject":"地盤の液状化","subitem_subject_scheme":"Other"},{"subitem_subject":"地盤改良工法","subitem_subject_scheme":"Other"},{"subitem_subject":"石灰系固化材","subitem_subject_scheme":"Other"},{"subitem_subject":"the Niigataken Chuetsu-oki Earthquake in 2007","subitem_subject_scheme":"Other"},{"subitem_subject":"rural sewerage facilitues","subitem_subject_scheme":"Other"},{"subitem_subject":"liquefaction of soil","subitem_subject_scheme":"Other"},{"subitem_subject":"soil improvement","subitem_subject_scheme":"Other"},{"subitem_subject":"lime admixture","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"2007年新潟県中越沖地震の被災事例で確認された地盤改良土の耐液状化性能","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2007年新潟県中越沖地震の被災事例で確認された地盤改良土の耐液状化性能"},{"subitem_title":"2007年新潟県中越沖地震の被災事例で確認された地盤改良土の耐液状化性能","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1601"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"28411","relation_version_is_last":true,"title":["2007年新潟県中越沖地震の被災事例で確認された地盤改良土の耐液状化性能"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:29.398913+00:00"}
