A series of in-situ soil investigation and laboratory soil tests were conducted to study effects of soil physical properties on the small-scale slope failure of the river embankment which occurred during heavy rain in June, 2007. Soil density and water content along soil profi le excavated into the embankment slope were measured by using soil sampler rod, and then a mass of soil was sampled from the damaged slope of the embankment to use in the laboratory soil tests. Physical properties of the soil such as density of soil particle, grain size distribution, and liquid and plastic limits were measured by the laboratory soil tests. Optimum water content and maximum dry density of soil were also measured by a compaction test to determine a degree of compaction along the soil profi le in the embankment slope. It was confirmed that the slope slide was, as well known, strongly aff ected by the physical properties of soil employed in the construction of the river embankment. This means a good evaluation and selection of soil in the embankment construction will lead a good mitigation of its possible hazard due to slope failure of the embankment. It was also reff ered that a plant cover on soil surface may eff ectively reduce a amount of infi ltration of rainwater into soil and possibility of slope failure or slide of the embankment.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"163393","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Uehara, Rurika"}]},{"nameIdentifiers":[{"nameIdentifier":"163394","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Toshihiro"}]}]},"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":"上原, るり香"}],"nameIdentifiers":[{"nameIdentifier":"163391","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森井, 俊広"}],"nameIdentifiers":[{"nameIdentifier":"163392","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":"61(1)_111-117.pdf","filesize":[{"value":"597.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"61(1)_111-117.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28401/files/61(1)_111-117.pdf"},"version_id":"fcdb9ec1-64cd-41e9-a808-77a5bff3a417"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"河川堤防","subitem_subject_scheme":"Other"},{"subitem_subject":"法面損傷","subitem_subject_scheme":"Other"},{"subitem_subject":"土質試験","subitem_subject_scheme":"Other"},{"subitem_subject":"土の締固め度","subitem_subject_scheme":"Other"},{"subitem_subject":"植生被覆","subitem_subject_scheme":"Other"},{"subitem_subject":"River embankment","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface slide of soil slope","subitem_subject_scheme":"Other"},{"subitem_subject":"Soil investigation and test","subitem_subject_scheme":"Other"},{"subitem_subject":"Degree of soil compaction","subitem_subject_scheme":"Other"},{"subitem_subject":"Plant cover on soil","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":"河川堤防法面の小規模すべり損傷事例にみる土質特性の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"河川堤防法面の小規模すべり損傷事例にみる土質特性の影響"},{"subitem_title":"河川堤防法面の小規模すべり損傷事例にみる土質特性の影響","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1600"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-02"},"publish_date":"2010-07-02","publish_status":"0","recid":"28401","relation_version_is_last":true,"title":["河川堤防法面の小規模すべり損傷事例にみる土質特性の影響"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:25.349615+00:00"}
