Moreover, we also made a comparison between the ground conditions of the reclaimed land and the natural ground, based on the geotechnical information database created uniquely.In the plateau examined, rapidly developed land, which was reclaimed from the 1970s, is included, and it became clear that such reclaimed areas are very vulnerable, judging from the N-values and the groundwater levels. It is presumable that such places are can be found in city areas all over the country, especially the newly developed residential areas. To prevent geotechnical disaster damage in each urban area, it is required to clarify how the landform was created and transformed afterwards. Thus, we must work out a master plan for disaster damage prevention, which can take care of not only the damages of underground lifeline networks, such as waterworks, sewers and gas pipes caused by the earthquakes but also daily failures caused by the vulnerability of the ground conditions.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"40728","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ITO, Yoji","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"40729","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IBUKA, Noritoshi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"40730","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMASHITA, Satoshi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"40731","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKAMURA, Dai","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人地盤工学会"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.3208/jgs.7.557","subitem_relation_type_select":"DOI"}}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2012 公益社団法人 地盤工学会"}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"伊藤, 陽司","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊深, 憲利","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山下, 聡","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"中村, 大","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-22"}],"displaytype":"detail","filename":"No34.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"No34.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/7893/files/No34.pdf"},"version_id":"e7c49548-ef42-44ca-a68d-86111c27a9dd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地形変遷","subitem_subject_scheme":"Other"},{"subitem_subject":"谷埋地盤","subitem_subject_scheme":"Other"},{"subitem_subject":"火山灰質土","subitem_subject_scheme":"Other"},{"subitem_subject":"geomorphic transition","subitem_subject_scheme":"Other"},{"subitem_subject":"valley filling ground","subitem_subject_scheme":"Other"},{"subitem_subject":"volcanic ash soil","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"都市域での地盤の成り立ちと性状-北海道東部，北見市中心部火山灰台地での検討-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"都市域での地盤の成り立ちと性状-北海道東部，北見市中心部火山灰台地での検討-","subitem_title_language":"ja"},{"subitem_title":"Chronological formation and quality of the ground in the urban area- The examination in the volcanic ash plateau, Kitami City, East Hokkaido, Japan -","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-08-18"},"publish_date":"2015-08-18","publish_status":"0","recid":"7893","relation_version_is_last":true,"title":["都市域での地盤の成り立ちと性状-北海道東部，北見市中心部火山灰台地での検討-"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:21:22.737912+00:00"}
