The authors, in order to settle the above problems, improved the usual type of test apparatus to be sheared repetitionally. Herein, some experimental results were shown using the improved test apparatus.\\nThe experiment was conducted in three kind of relative densities (Loose state: D_r=25%, Medium state: D_r=54%, and Dense state: D_r=79%), and air dry TOYOURA uniform sand was used. The loading method of shear test are included three cases, such as: 1) Single direction shearing (Usual Type), 2) Repetitional shearing under the same displacement cycles (Constant cycles), 3) Repetitional shearing under the different displacement cycles (Increasing cycles).\\nThe following results are obtained: 1) The shearing resistance τ_m increases as the repetitional cycles N increases, when the repetitional displacement was smaller than the maximum shearing displacement. 2) The angle of shearing resistance φ was influenced distinctly by repetitional shear test. The angle φ show a slight increase in comparison with the single direction shearing when the repetitional displacement was smaller than the failure displacement. 3) The hystorical damping factor h was shown in the range of h=29～32%.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学工学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/1989"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0389-102X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN0025048X"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学工学部紀要"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueNumber":"30","bibliographicPageEnd":"22","bibliographicPageStart":"13"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No30p13.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2002011/files/No30p13.pdf"},"version_id":"c3547bb2-3fda-4d56-a3e5-3834fea799c8"}]},"item_title":"乾燥砂の繰り返し一面セン断試験に関する実験的研究","item_type_id":"15","owner":"1","path":["1642837860996","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-09-16"},"publish_date":"2007-09-16","publish_status":"0","recid":"2002011","relation_version_is_last":true,"title":["乾燥砂の繰り返し一面セン断試験に関する実験的研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-02-14T21:21:07.617843+00:00"}
