We conducted an ice jam experiment which used mixed real ice with ice sheet and frazil slush. In order to clarify the effect of frazil slush, the\nexperimental results show that ice velocity, number of ice, floods area variations, water level variations. In the case of containing frazil slush, they accumulate underneath the flowing ice sheet, sticking to each other and flowing down as large blocks. And, Ice sheet velocity is slowed down because the shape resistance increases. In the case of containing frazil slush, the ice flows downstream as large ice blocks. When ice jam is generated, the upstream floods area velocity increases and floods rapidly.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会","subitem_publisher_language":"ja"}]},"item_3_relation_208":{"attribute_name":"論文ID(NAID)","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"40022430486","subitem_relation_type_select":"NAID"}}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_3_source_id_187":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-467X","subitem_source_identifier_type":"EISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 隆司","creatorNameLang":"ja"},{"creatorName":"YAMADA, Ryuji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"吉川, 泰弘","creatorNameLang":"ja"},{"creatorName":"ヨシカワ, ヤスヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"YOSHIKAWA, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"89971","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50414149","nameIdentifierScheme":"KAKEN - 研究者検索","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000050414149"}]},{"creatorNames":[{"creatorName":"小池, 太郎","creatorNameLang":"ja"},{"creatorName":"KOIKE, Taro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"横山, 洋","creatorNameLang":"ja"},{"creatorName":"YOKOYAMA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"38355","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000018330021","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000018330021"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2021-05-26"}],"displaytype":"detail","filename":"dobokuB1_Vol.76,No.2,I_169-I_174,2020.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"土木学会論文集B1(水工学) Vol.76, No.2, I_169-I_174, 2020","objectType":"fulltext","url":"https://kitami-it.repo.nii.ac.jp/record/2000055/files/dobokuB1_Vol.76,No.2,I_169-I_174,2020.pdf"},"version_id":"362916c9-7919-429f-9daf-63711c75b397"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ice jam","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"bridge piers","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"water level variation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"real ice","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"氷板と晶氷が混在した橋脚部におけるアイスジャム氾濫実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"氷板と晶氷が混在した橋脚部におけるアイスジャム氾濫実験","subitem_title_language":"ja"},{"subitem_title":"ICE JAM FLOOD EXPERIMENT USING MIXED REAL ICE WITH ICE SHEET AND FRAZIL SLUSH AROUND BRIDGE PIERS","subitem_title_language":"en"}]},"item_type_id":"3","owner":"15","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-05-26"},"publish_date":"2021-05-26","publish_status":"0","recid":"2000055","relation_version_is_last":true,"title":["氷板と晶氷が混在した橋脚部におけるアイスジャム氾濫実験"],"weko_creator_id":"15","weko_shared_id":3},"updated":"2022-12-13T02:24:39.188675+00:00"}
