To examine the mechanical properties of sea and lake bottom sediments, the handy vane shear and cone penetration tests were performed for the core samples on board. To evaluate the sample disturbance due to the exsolution of dissolved gas during sampling, the relations between the concentration of dissolved gas in the pore water and the strength were also examined. Moreover, laboratory tests which simulate the stress relief from bringing the samples to the sea or lake surface were also performed. Test results showed that the strength of soils become lower with the increase in degree of gas saturation on both on-board and laboratory tests. It was also showed that the in-situ strength can be estimated roughly from the disturbed sample.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "40790", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "YAMASHITA, Satoshi", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40791", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "DEWA, Hironobu", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40792", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "HACHIKUBO, Akihiro", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40793", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "MINAMI, Hirotsugu", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40794", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "KATAOKA, Satsuki", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40795", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "KAWAGUCHI, Takayuki", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40796", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SAKAGAMI, Hirotoshi", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40797", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "TAKAHASH, Nobuo", "nameLang": "en"}]}, {"nameIdentifiers": [{"nameIdentifier": "40798", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SHOJI, Hitoshi", "nameLang": "en"}]}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "公益社団法人地盤工学会"}]}, "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.7.503", "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_3_subject_196": {"attribute_name": "日本十進分類法", "attribute_value_mlt": [{"subitem_subject": "568", "subitem_subject_scheme": "NDC"}]}, "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": "山下, 聡", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "44837", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "174673", "nameIdentifierScheme": "KAKEN", "nameIdentifierURI": "https://nrid.nii.ac.jp/ja/nrid/1000000174673 "}]}, {"creatorNames": [{"creatorName": "出羽, 寛信", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "40782", "nameIdentifierScheme": "WEKO"}]}, {"creatorAffiliations": [{"affiliationNameIdentifiers": [{"affiliationNameIdentifier": "", "affiliationNameIdentifierScheme": "ISNI", "affiliationNameIdentifierURI": "http://www.isni.org/isni/"}], "affiliationNames": [{"affiliationName": "", "affiliationNameLang": "ja"}]}], "creatorNames": [{"creatorName": "八久保, 晶弘", "creatorNameLang": ""}, {"creatorName": "八久保, 晶弘", "creatorNameLang": ""}], "familyNames": [{"familyName": "八久保", "familyNameLang": ""}, {"familyName": "八久保", "familyNameLang": ""}], "givenNames": [{"givenName": "晶弘", "givenNameLang": ""}, {"givenName": "晶弘", "givenNameLang": ""}], "nameIdentifiers": [{"nameIdentifier": "89765", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "50312450", "nameIdentifierScheme": "KAKEN -
