Author of a member of JSCE team traced the surface faults and investigated into damage to civil engineering structures(brigdes, dames, lifeline facilities) caused fault movements immediately after the earthquake. This reports describes the characteristic aspects of the earthquake disaster the civil engineering structures by the 1999 Ji-Ji earthquake as follows. (l)The surface raptures caused by the reverse earthquake fault appeared in the huge area and casued catastrophic damage to civil engineering structures (bridges, dams, buildings houses and lifeline facilities). (2)The road bridges were totally collapsed and more than 30 bridges suffered comparative light damages which needed repairements after the earthquake by the surface faulting. The concrete gravity dam with a height of 25m was also totally collapsed by the surface faulting. The total collapse of the bridges and the dame, which were directly caused by the fault movement is the first experience. (3)Lifeline system such as electricity suffered severe damage, and slope failures collapsed transmission towers, while the surface rupture damages a number of facilities of main switchyard for the electricity distibution. (4)Facilities of Taichung port were damaged mainly due to soilliquefaction, and a numerous number of huge slope failures occured in the mountainous area and buried villages and valleys, resulted in loss of many lives. (5)The Ji-Ji earthquake will rise a new technical as well as social subject of the earthquake resistant design of structures against surface ruptures caused by fault activities. We have to review the current technologies and to develop a new methodologies to prevent the damage to various kinds of structures against the surface faultings.","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":"岩楯, 敞広"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉嶺, 充俊"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-04-14"}],"displaytype":"detail","filename":"20024-072-007.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20024-072-007.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/5770/files/20024-072-007.pdf"},"version_id":"49073b76-b200-46a9-ba99-872087213374"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"台湾集集地震","subitem_subject_scheme":"Other"},{"subitem_subject":"地震被害調査","subitem_subject_scheme":"Other"},{"subitem_subject":"地震断層","subitem_subject_scheme":"Other"},{"subitem_subject":"車籠埔断層","subitem_subject_scheme":"Other"},{"subitem_subject":"石岡ダム","subitem_subject_scheme":"Other"},{"subitem_subject":"Ji-Ji (Taiwan) Earthquake","subitem_subject_scheme":"Other"},{"subitem_subject":"Earthquake Damage Investigation","subitem_subject_scheme":"Other"},{"subitem_subject":"Earthquake Fault","subitem_subject_scheme":"Other"},{"subitem_subject":"Chelungpu Thrust","subitem_subject_scheme":"Other"},{"subitem_subject":"Shye-Gang Dam","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":"台湾集集地震土木構造物の被害と特徴","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"台湾集集地震土木構造物の被害と特徴"}]},"item_type_id":"3","owner":"3","path":["1335"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-01"},"publish_date":"2017-05-01","publish_status":"0","recid":"5770","relation_version_is_last":true,"title":["台湾集集地震土木構造物の被害と特徴"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T16:57:56.896334+00:00"}
