The major deformations of the host rock masses containing underground caverns originate from the normal and shear movements among the walls of discontinuities. Therefore, in the numerical simulations of the deformation behavior of underground structures, how to accurately model the discontinuities becomes a key problem. In this study, a 2-D distinct element code, UDEC, was used to analyze the deformation behavior of an underground cavern of a pumped storage power plant, based on in-situ geological data. The validity of numerical simulation was evaluated by comparing the numerical results with the site measurement data at two cross-sections of the cavern. Some local deformation behavior of the cavern affected by the characteristics of discontinuity distributions was discussed. The influences of cross-sectional shape of the cavern and the orientation of initial ground stress on the performance of cavern were evaluated. The simulation results revealed that the orientation, position and density of discontinuities as well as the cross-sectional shape of a carven influences its deformation behavior and stability significantly.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"SOILS AND FOUNDATIONS, 50(5), pp.609-621; 2010","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japanese Geotechnical Society"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3208/sandf.50.609","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2010 The Japanese Geotechnical Society"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00700879","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00380806","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"18811418","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"地盤工学会"}]},"item_2_version_type_16":{"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":"Li, Bo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jiang, Yujing"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanabashi, Yoshihiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamashita, Yuji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"SAF50_609.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SAF50_609.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/11492/files/SAF50_609.pdf"},"version_id":"1e4d9786-0ceb-429c-8559-9c254fd27cfd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Deformation","subitem_subject_scheme":"Other"},{"subitem_subject":"Discontinuity","subitem_subject_scheme":"Other"},{"subitem_subject":"Distinct element method","subitem_subject_scheme":"Other"},{"subitem_subject":"Excavation","subitem_subject_scheme":"Other"},{"subitem_subject":"Measurement","subitem_subject_scheme":"Other"},{"subitem_subject":"Underground cavern","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"BEHAVIOR OF LARGE SCALE UNDERGROUND CAVERN LOCATED IN JOINTED ROCK MASSES EVALUATED BY USING DISTINCT ELEMENT METHOD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"BEHAVIOR OF LARGE SCALE UNDERGROUND CAVERN LOCATED IN JOINTED ROCK MASSES EVALUATED BY USING DISTINCT ELEMENT METHOD"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-28"},"publish_date":"2012-02-28","publish_status":"0","recid":"11492","relation_version_is_last":true,"title":["BEHAVIOR OF LARGE SCALE UNDERGROUND CAVERN LOCATED IN JOINTED ROCK MASSES EVALUATED BY USING DISTINCT ELEMENT METHOD"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:02:14.728276+00:00"}
