(2005) is extended so that time-dependent behavior of brittle material can be taken into account, with special attention to the numerical analysis of an excavation damage zone (EDZ) around a tunnel, which is a major concern in assessing the safety of underground repositories. The present model is capable of reproducing the three characteristic stages of creep behavior (i.e., primary, secondary and tertiary creep) commonly observed in laboratory creep tests. Using the present model, sub-critical microcrack growth parameters (i.e. n and A) can be determined for Inada granite by fitting the numerical results of elapse time to failure versus the creep stress ratio curve with the experimental data under both dry and wet conditions. It is found that moisture has a significant influence on the parameter A rather than the parameter n. Use of the extended model makes it possible to analyze not only the extension of microcrack length, but also the development of the excavation damage zone (EDZ) around tunnels as a function of time. The disturbed zones mainly develop in the sidewalls of the tunnel in the case that the vertical stress is larger than the horizontal stress.","subitem_description_type":"Other"}]},"item_120_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_120_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_120_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24561/00016122","subitem_identifier_reg_type":"JaLC"}]},"item_120_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学工学部"}]},"item_120_publisher_12":{"attribute_name":"出版者名（別言語）","attribute_value_mlt":[{"subitem_publisher":"Faculty of Engineering, Saitama University"}]},"item_120_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18804446","subitem_source_identifier_type":"ISSN"}]},"item_120_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_120_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"ODA, Masanobu"},{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"OKUI, Yoshiaki"}]},"item_120_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"KY-AN00095842-39-19"}]},"item_120_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科環境科学・社会基盤部門"},{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"埼玉大学大学院理工学研究科環境科学・社会基盤部門"}]},"item_120_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"},{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_120_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2006-7"}]},"item_120_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小田, 匡寛"},{"creatorName":"オダ, マサノブ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"26250","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"GOLSHANI, Aliakbar"}],"nameIdentifiers":[{"nameIdentifier":"26251","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"奥井, 義昭"},{"creatorName":"オクイ, ヨシアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"16719","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"dmMusmBx","nameIdentifierScheme":"研究者総覧","nameIdentifierURI":"http://s-read.saitama-u.ac.jp/researchers/pages/researcher/dmMusmBx"}]},{"creatorNames":[{"creatorName":"TAKEMURA, Takato"},{"creatorName":"タケムラ, タカト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"26252","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":"2018-01-24"}],"displaytype":"detail","filename":"KY-AN00095842-39-19.pdf","filesize":[{"value":"817.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KY-AN00095842-39-19.pdf","url":"https://sucra.repo.nii.ac.jp/record/16128/files/KY-AN00095842-39-19.pdf"},"version_id":"84d28543-3799-414b-b07c-174f7458335e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Time-dependent behavior","subitem_subject_scheme":"Other"},{"subitem_subject":"Brittle material","subitem_subject_scheme":"Other"},{"subitem_subject":"Creep failure","subitem_subject_scheme":"Other"},{"subitem_subject":"Numerical Simulation","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Numerical simulation of an excavation disturbed zonearound a tunnel in brittle rock<速報>","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Numerical simulation of an excavation disturbed zonearound a tunnel in brittle rock<速報>"}]},"item_type_id":"120","owner":"3","path":["518"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-21"},"publish_date":"2008-03-21","publish_status":"0","recid":"16128","relation_version_is_last":true,"title":["Numerical simulation of an excavation disturbed zonearound a tunnel in brittle rock<速報>"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T18:51:33.193057+00:00"}
