The best way for such boats to escape from tsunamis is to take refuge at the deep sea. But in case that tsunami's origin is near the coast, there is not enough time for small boats in fishing port to take refuge at the deep sea, before the tsunamis reach the coast. In this report, authors discuss mooring boats at wharfs, in such a way to prevent damages by tsunamis to them, based on the results of experiments in which mooring forces of a fishing boat were measured. If amplitude of tsunamis at wharfs is less than 1.5 m and water surface elevation moderately cahnges, it will be effective to moor small boats at a wharf with long ropes which are not strained under normal conditions. However in case that tsunamisadvance like hydraulic bore, it seems inevitable that mooring ropes will be broken by shock forces due to the hydraulic bore.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"これまで述べたことから次の事が言える。(1) 津波の流速が大きく水位変動が小さい場合,船の慣性によって,緩く張られた係留ラインに衝撃的な張力が発生する。しかし,流速が小さく水位変動が大きい場合では張力は静的であり,流体力を無視した簡便な計算法によってある程度推定できることが実験によって確認された。この場合,係留ラインの伸びが無視し得ない時は,係留ラインの弾塑性を考慮することが必要であり,本計算法は適用できない。(2) 船を係留する場合,係留ラインを緊張させず長めにしておくと静的水面変動に対して有効であることが,実験及び計算により確認された。(3) 津波が段波状になって来襲する場合は特に大きい衝撃力が働くため,大型船の係留ラインの破断を防ぐのは困難であろう。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産工学研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Research Institute of Fisheries Engineering","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nrife_gd_6_171","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010320593","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00329681","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0389-2344","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakayama, Akiyoshi","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"中山, 哲嚴","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"ナカヤマ, アキヨシ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Nakayama","familyNameLang":"en"},{"familyName":"中山","familyNameLang":"ja"},{"familyName":"ナカヤマ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Akiyoshi","givenNameLang":"en"},{"givenName":"哲嚴","givenNameLang":"ja"},{"givenName":"アキヨシ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1905","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40372065","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40372065"}]},{"creatorNames":[{"creatorName":"Yamamoto, Masaaki","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"山本, 正昭","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"ヤマモト, マサアキ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Yamamoto","familyNameLang":"en"},{"familyName":"山本","familyNameLang":"ja"},{"familyName":"ヤマモト","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Masaaki","givenNameLang":"en"},{"givenName":"正昭","givenNameLang":"ja"},{"givenName":"マサアキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3502","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"津波による漁船の係留ラインの張力について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"津波による漁船の係留ラインの張力について","subitem_title_language":"ja"},{"subitem_title":"On Mooring Forces of a Fishing Boat due to Tsunamis","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955731445"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-19"},"publish_date":"2024-06-19","publish_status":"0","recid":"2008055","relation_version_is_last":true,"title":["津波による漁船の係留ラインの張力について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-16T04:35:17.760602+00:00"}
