In the investigation, sediments with methane hydrates were sampled, and several kinds of tests (cone penetration, vane shear, bender element, uniaxial compression tests) were performed on the board. At the same time, samples were also retrieved from the grounds without methane hydrates. Then, the soil strengths and physical properties for both samples were compared. As a result, it was found that the soil strengths of surface sediments with methane hydrates were lower than those without methane hydrates regardless of the depth. It would seem that this is because the effect of the disturbance by emission of gas and water and pressure release during the sampling.","subitem_description_type":"Abstract"}]},"item_3_description_194":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"37493","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mikhail, Grachev","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"37494","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KATAOKA, Satsuki","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"37495","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMASHITA, Satoshi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"37496","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MINAMI, Hirotsugu","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"37497","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NISHIO, Shin’ya","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"37498","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ABE, Toru","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"37499","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YOKOYAMA, Tatsuya","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"37500","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HYODO, Masayuki","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"地盤工学会"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.3208/jgs.2.95","subitem_relation_type_select":"DOI"}}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"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":"片岡, 沙都紀","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山下, 聡","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"南, 尚嗣","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"西尾, 伸也","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"安部, 透","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"横山, 幸也","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"兵動, 正幸","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-22"}],"displaytype":"detail","filename":"280yamashita.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"280yamashita.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/7350/files/280yamashita.pdf"},"version_id":"dea836ec-9ab2-4d71-a0a5-ed23fed6d9d5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"バイカル湖","subitem_subject_scheme":"Other"},{"subitem_subject":"メタンハイドレート","subitem_subject_scheme":"Other"},{"subitem_subject":"現地調査","subitem_subject_scheme":"Other"},{"subitem_subject":"現場計測","subitem_subject_scheme":"Other"},{"subitem_subject":"試料の乱れ","subitem_subject_scheme":"Other"},{"subitem_subject":"lake Baikal","subitem_subject_scheme":"Other"},{"subitem_subject":"methane hydrate","subitem_subject_scheme":"Other"},{"subitem_subject":"site investigation","subitem_subject_scheme":"Other"},{"subitem_subject":"measurement","subitem_subject_scheme":"Other"},{"subitem_subject":"sample disturbance","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":"バイカル湖表層型メタンハイドレート賦存堆積土の地盤工学的性質","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"バイカル湖表層型メタンハイドレート賦存堆積土の地盤工学的性質","subitem_title_language":"ja"},{"subitem_title":"Geotechnical properties of the shallow type methane hydrate-bearing sediments in the Lake Baikal","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-04-02"},"publish_date":"2009-04-02","publish_status":"0","recid":"7350","relation_version_is_last":true,"title":["バイカル湖表層型メタンハイドレート賦存堆積土の地盤工学的性質"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:22:22.689145+00:00"}
