Therefore, analyses of the stability of roof and investigation of the influence on stability are very important. In mining practice, stratified host rock mass with a layer of weak rock is not uncommon. There are cases where a layer of weak rock is located near the opening. In general, a weak layer has larger deformation for lower stiffness, and has low strength properties. In such a case, it is clear that the weak layer influences the roof stability. The purpose of this study is to investigate the influence of both the depth and thickness of a weak layer on the stress distribution and the failure characteristics of roof with a qualitative experimental model. A stratified rock structure with a horizontal, single weak layer is assumed in this model. The beam analysis is then developed on the basis of a model experiment, and the predications were compared with the experimental results.","subitem_description_type":"Other"}]},"item_10002_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"秋田大学工学資源学部"}]},"item_10002_source_id_27":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13457241","subitem_source_identifier_type":"ISSN"}]},"item_10002_source_id_35":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11410906","subitem_source_identifier_type":"NCID"}]},"item_10002_version_type_37":{"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":"川辺, 金光"}],"nameIdentifiers":[{"nameIdentifier":"5441","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山下, 秀"}],"nameIdentifiers":[{"nameIdentifier":"5442","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"杉本, 文男"}],"nameIdentifiers":[{"nameIdentifier":"5443","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井, 忠男"}],"nameIdentifiers":[{"nameIdentifier":"5444","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KAWABE, Kanemitsu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5445","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YAMASHITA, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5446","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SUGIMOTO, Fumio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5447","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"IMAI, Tadao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5448","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"koushi21a.pdf","filesize":[{"value":"820.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"koushi21a.pdf","url":"https://air.repo.nii.ac.jp/record/1511/files/koushi21a.pdf"},"version_id":"0aa0484a-0741-4352-a764-237aa516bfcc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地下空洞","subitem_subject_scheme":"Other"},{"subitem_subject":"天盤","subitem_subject_scheme":"Other"},{"subitem_subject":"弱層","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":"弱層を有する地下空洞天盤の安全性について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"弱層を有する地下空洞天盤の安全性について"}]},"item_type_id":"10002","owner":"3","path":["768"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-12-18"},"publish_date":"2008-12-18","publish_status":"0","recid":"1511","relation_version_is_last":true,"title":["弱層を有する地下空洞天盤の安全性について"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:18:05.661842+00:00"}
