Since upgrading of individual elements has complex implications for the whole system，the possibility of damage exists even for parts that suffer no direct damage at the time of a disaster. Among the urban functions，especially the so -called life lines- the functions related to daily life utility systems like electricity，gas and water supply lines，transportation and communication lines - have generally been greatly expanded. Furthermore，they cover a wide area，and when we consider their geographical indeterminacy，it is becoming extremely difficult to uniformly strengthen and secure the earthquake resistance of the system as a whole. When we have to examine anti -earthquake counter measure to these life line systems，disaster prevention emphasizes recovery measures - besides giving due consideration to strengthening the earthquake- proof design of the facilities- in order to shorten the period of intermittence caused by the damage. In this paper，we attempt a thorough inquiry into methods of recovery from damage to electric power lines，which occupy a crucial position among the life line systems，from the viewpoint of earthquake- proof design.","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"postprint","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京都立大学都市研究センター"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00134354","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03863506","subitem_source_identifier_type":"ISSN"}]},"item_3_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":"三森, 友彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 浩平"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-17"}],"displaytype":"detail","filename":"20024-044-007.pdf","filesize":[{"value":"703.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20024-044-007.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/5388/files/20024-044-007.pdf"},"version_id":"ef214f7e-28e0-410e-ac18-83a8915dada0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Life Line System","subitem_subject_scheme":"Other"},{"subitem_subject":"Disaster Recovery Method","subitem_subject_scheme":"Other"},{"subitem_subject":"Electric Power System","subitem_subject_scheme":"Other"},{"subitem_subject":"Redundancy","subitem_subject_scheme":"Other"},{"subitem_subject":"Positive Back Up","subitem_subject_scheme":"Other"},{"subitem_subject":"Negative Back Up","subitem_subject_scheme":"Other"},{"subitem_subject":"ライフラインシステム","subitem_subject_scheme":"Other"},{"subitem_subject":"災害復旧法","subitem_subject_scheme":"Other"},{"subitem_subject":"電力網","subitem_subject_scheme":"Other"},{"subitem_subject":"多重化","subitem_subject_scheme":"Other"},{"subitem_subject":"積極的支援","subitem_subject_scheme":"Other"},{"subitem_subject":"積極的支援","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"大都市ライフラインシステムの災害復旧シミュレーションについて","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大都市ライフラインシステムの災害復旧シミュレーションについて"}]},"item_type_id":"3","owner":"3","path":["1304"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-31"},"publish_date":"2017-03-31","publish_status":"0","recid":"5388","relation_version_is_last":true,"title":["大都市ライフラインシステムの災害復旧シミュレーションについて"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T17:19:46.528880+00:00"}
