Hudson's Formula is used usually as a required weight of armor blocks. Parameters of the formula containe material density, slope of mound and characteristic of block shape. For searching about the effect of density, the model experiment in a wave tank using various density blocks from 2.3 gr/cm3 to 3.9 gr/cm3 was carried out, and obtained data was analized by multi-regression analysis. As a result, I find that it is necessary to alter the determing method of designing wave height, and that the required block weight on a rear slope have closer relationship with the weight in the air than the weight in the water.","subitem_description_language":"en","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_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nrife_gd_14_89","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/2010500409","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":"山本, 正昭","creatorNameLang":"ja"}],"familyNames":[{"familyName":"山本","familyNameLang":"ja"}],"givenNames":[{"givenName":"正昭","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"rubble mound breakwater; armor block; stability test of blocks; higher density concrete; Hudson's Formula","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":"item_resource_type","attribute_value_mlt":[{"resourcetype":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"大波浪に対する捨ブロック堤の安定に関する実験的研究(2)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大波浪に対する捨ブロック堤の安定に関する実験的研究(2)","subitem_title_language":"ja"},{"subitem_title":"Experimetal Study on Stability of Rubble Mound Breakwater against High Waves (II) -Study for High Density Concrete-","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":"2008104","relation_version_is_last":true,"title":["大波浪に対する捨ブロック堤の安定に関する実験的研究(2)"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-25T01:57:40.756533+00:00"}
