The significance of such life line system damage and its effects on the evaluation after the disaster are discussed. 1. Earthquake resistant characteristics of roads In urban regions, the loss of faculty is the main problem, since e.g. slope collapse alongside roads severely affects evacuation When slopes down from the roads collapse. the entire faculty is practically lost. If slopes up from the road collapse, falling stones and soil will also close the road to traffic needed for various postdisaster activities，s uch as fire-fighting, urgent rescue operations, or the delivery of goods. Close to 300km of Tokyo's roads run along slopes over 3m high, with an angle of over 30 degrees. Out of these, a bout 10km are prone to collapse. In 1973, an investigation by the Tokyo Disaster Prevention Conference revealed that over twenty-two thousand dwelling houses could be affected by slope collapses. Most of the slopes have a natural subsurface covered with stone masonry. While several methods of slope collapse estimation are valid, a method based on micro-tremors, used in the study of aseismicity of fill-up pground, is proposed for exemining a great variety of slopes. This method, which makes collapse  estimation easy, is validated by analysis of response calculation (with one degree freedom)  2. Earthquake resistant characteristics of bridges The method described in the Kanagawa prefecture report introducing the Delphi opinionnaire is seen as one of the most reliable regarding earthquake resistance criteria. The 1978 Tokyo Disaster Prevention Conference reported on a method for estimating the collapse of bridges based on quantification analysis. From nine bridges that collapsed under strong earthquake vibration, five bridges that nearly collapsed and many other bridges in Japan that resisted collapse, the following criteria for collapse were obtained: a ) Ground condition b) liquefaction c ) structural system of main girder d) support e ) height of pier and abutment f ) number of spans g) crown width h) intensity scale i ) foundation structure. The Kanagawa prefecture report mentioned above partially covers these criteria.","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":"国井, 隆弘"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-12-26"}],"displaytype":"detail","filename":"20024-038-005.pdf","filesize":[{"value":"586.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20024-038-005.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/5180/files/20024-038-005.pdf"},"version_id":"0590d738-0830-4187-8ac0-dbc1964f5790"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Road","subitem_subject_scheme":"Other"},{"subitem_subject":"Bridge","subitem_subject_scheme":"Other"},{"subitem_subject":"Slope","subitem_subject_scheme":"Other"},{"subitem_subject":"Criterion of Judgement","subitem_subject_scheme":"Other"},{"subitem_subject":"Estimation of Collapse","subitem_subject_scheme":"Other"},{"subitem_subject":"道路","subitem_subject_scheme":"Other"},{"subitem_subject":"橋梁","subitem_subject_scheme":"Other"},{"subitem_subject":"斜面","subitem_subject_scheme":"Other"},{"subitem_subject":"判断基準","subitem_subject_scheme":"Other"},{"subitem_subject":"崩壊予測","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":"道路・橋梁","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"道路・橋梁"}]},"item_type_id":"3","owner":"3","path":["807"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-01-10"},"publish_date":"2017-01-10","publish_status":"0","recid":"5180","relation_version_is_last":true,"title":["道路・橋梁"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T17:44:55.356664+00:00"}
