Naturally deposited soils are usually at overconsolidated state and those soils are mostly at structured state. In order to express loss of overconsolidation and decay of soil structure with loading, the super-subloading surfaces were introduced to the Cam-clay model. The following findings were obtained : (1) when dewatering exceeds a certain level, delayed consolidation with huge settlement is observed, which is concluded as the results of plastic softening of soils with plastic volume compression. (2) When multi-layered system is the case, delayed compression/consolidation of lower layers may occur even after the finish of the settlement of upper layers. This is due to the delay of propagation of the increase of effective stress that occurs due to dewatering.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/8632"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "土木学会", "subitem_publisher_language": "ja"}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "土木編集第07010号", "subitem_rights_language": "ja"}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0289-7806", "subitem_source_identifier_type": "PISSN"}]}, "item_10_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_1615787544753": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "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": "金田, 一広", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "18635", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KANEDA, Kazuhiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18636", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "山田, 正太郎", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "18637", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YAMADA, Shotaro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18638", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "浅岡, 顕", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "18639", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ASAOKA, Akira", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18640", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "v743_p89-103.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "v743_p89-103.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/6963/files/v743_p89-103.pdf"}, "version_id": "e1808dcc-87b3-4dcd-8eeb-c5aefcd97672"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "land subsidence", "subitem_subject_scheme": "Other"}, {"subitem_subject": "one dimensional consolidation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "naturally sedimented clay", "subitem_subject_scheme": "Other"}, {"subitem_subject": "dewatering", "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": "地下水位低下に起因する地盤の遅れ圧密沈下のメカニズム", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "地下水位低下に起因する地盤の遅れ圧密沈下のメカニズム", "subitem_title_language": "ja"}]}, "item_type_id": "10", "owner": "1", "path": ["322"], "permalink_uri": "http://hdl.handle.net/2237/8632", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-08-07"}, "publish_date": "2007-08-07", "publish_status": "0", "recid": "6963", "relation": {}, "relation_version_is_last": true, "title": ["地下水位低下に起因する地盤の遅れ圧密沈下のメカニズム"], "weko_shared_id": -1}
