At first a big landslide occurred in the upper slope of the Sumikawa hot spring. Clearly the landslide was triggered mainly by snow melt and additionally by 110mm rainfall. The total volume of the slid soil mass was estimated to be 594,000,000m^3. From the toe area of the landslide a soil mass of 116,000,000m^3 flowed downward several times as debris flows along the Sumikawa torrent. Chemical analysis of the water contained in the debris deposit in the landslide area should provide an effective measure of identifying the origin of the water. Chemical analysis results showed that the water in the debris deposit did not originate directly from rainfall and snow melt but came from stored groundwater. This report interprets also the physical and mechanical properties of the unstable debris deposits in the landslide area as a source material of the debris flows. Various geotechnical investigations were performed in order to analyze the mechanism and the process of the debris flows. The shear strength parameters of debris deposits in the upper part and the toe part of the landslide area were determined by using a ring shear apparatus.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"161086","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Marui, Hideaki"}]},{"nameIdentifiers":[{"nameIdentifier":"161087","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Naoki"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学積雪地域災害研究センター"}]},"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":"AN00183327","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03877892","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"丸井, 英明"}],"nameIdentifiers":[{"nameIdentifier":"161084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡部, 直喜"}],"nameIdentifiers":[{"nameIdentifier":"161085","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":"20_10-24.pdf","filesize":[{"value":"864.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20_10-24.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28026/files/20_10-24.pdf"},"version_id":"e91a33d5-e2ba-4f53-87e3-990846fbc681"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"landslide caused by snow melting","subitem_subject_scheme":"Other"},{"subitem_subject":"debris flow","subitem_subject_scheme":"Other"},{"subitem_subject":"ring shear apparatus","subitem_subject_scheme":"Other"},{"subitem_subject":"residual strength","subitem_subject_scheme":"Other"},{"subitem_subject":"electric conductivity","subitem_subject_scheme":"Other"},{"subitem_subject":"chemical analysis of the water","subitem_subject_scheme":"Other"},{"subitem_subject":"融雪地すべり","subitem_subject_scheme":"Other"},{"subitem_subject":"岩層流","subitem_subject_scheme":"Other"},{"subitem_subject":"リング剪断試験","subitem_subject_scheme":"Other"},{"subitem_subject":"残留強度","subitem_subject_scheme":"Other"},{"subitem_subject":"電気伝導度","subitem_subject_scheme":"Other"},{"subitem_subject":"水質分析","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":"1997年八幡平土石流と地質・土質並びに水質特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"1997年八幡平土石流と地質・土質並びに水質特性"},{"subitem_title":"1997年八幡平土石流と地質・土質並びに水質特性","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1563"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-08"},"publish_date":"2016-03-08","publish_status":"0","recid":"28026","relation_version_is_last":true,"title":["1997年八幡平土石流と地質・土質並びに水質特性"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:57:56.800360+00:00"}
