A simulation model is composed of 5 layers that values of physical properties are different, and different analytical parameters are gave to each layer. These values are decided by doing the simulation analysis of biaxial compression test by DEM in advance of excavationg simulation. Using the ground model and these analytical conditions, we tried to simulate a tunnel excavation, and it is recognized that the deformation of surrounding ground of tunnel and the effect of ground surface are inhibited by improving the layers of low-stiffness.","subitem_description_type":"Other"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"24939","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ise, Kentaro"}]}]},"item_7_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_7_version_type_19":{"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":"伊世, 健太郎","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"楠見, 晴重","creatorNameLang":"ja"},{"creatorName":"Kusumi, Harushige","creatorNameLang":"en"}],"familyNames":[{"familyName":"楠見","familyNameLang":"ja"},{"familyName":"Kusumi","familyNameLang":"en"}],"givenNames":[{"givenName":"晴重","givenNameLang":"ja"},{"givenName":"Harushige","givenNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100DG-20100100-00.pdf","filesize":[{"value":"934.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100DG-20100100-00.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/11242/files/KU-1100DG-20100100-00.pdf"},"version_id":"3e098f1e-48f6-4f5c-a6ea-954f0812de20"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"shallow tunnel","subitem_subject_scheme":"Other"},{"subitem_subject":"distinct element method","subitem_subject_scheme":"Other"},{"subitem_subject":"simulation analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"multilayered gound","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"個別要素法を用いた多層地盤中における浅層トンネルの掘削シミュレーション解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"個別要素法を用いた多層地盤中における浅層トンネルの掘削シミュレーション解析","subitem_title_language":"ja"}]},"item_type_id":"7","owner":"1","path":["1593"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-06-30"},"publish_date":"2010-06-30","publish_status":"0","recid":"11242","relation_version_is_last":true,"title":["個別要素法を用いた多層地盤中における浅層トンネルの掘削シミュレーション解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2024-01-15T06:00:11.503860+00:00"}
