While in practical case, sometimes it is necessary to obtain some soil data using the general type (static type) of simple shear test apparatus. The authors, in view of the latter case, conducted experimentally on the repetitional simple shear test in the range of large shearing strain \u03b3=1\uff5e5% using the general type of simple shear test apparatus.\\nThe experiment was conducted in three kind of relative densities (Loose state: D_r=40%, Medium state: D_r=60%, Dense state: D_r=80%), and air dry TOYOURA uniform sand was used. Two cases of shearing test were conducted, such as : 1) Singular direction shearing (Usual test), 2) Repetitional shearing under constant cycles.\\nThe following results are obtained : 1) The interparticle friction angle of sand \u03c6_\u03bc is obtained in the range of \u03c6_\u03bc = 18.5\uff5e25.4 (\u00b0). The smaller value was obtained in the cases of increasing the normal stress applied in simple shear test \u03c3_v, or decreasing the relative density D_r. 2) The equivalent hysteretic damping factor h is shown the range of h=20\uff5e29 (%), the value h increases at larger repetitional shear strain \u03b3_a, or at smaller normal stress applied in simple shear test \u03c3_v. 3) The relationship between equivalent hysteretic damping h and shearing modulus G are approximately linear at nearly 10 cycles. 4) It could be considered that the change of the repetitional shearing characteristics are influenced not only by the change of rearrangement of particles due to loading but aslo by the change of interparticle friction angle \u03c6_\u03bc owing to particle crushing.","subitem_description_type":"Other"},{"subitem_description":"\u7d00\u8981\u8ad6\u6587","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8"}]},"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/20.500.12000/1987"}]},"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":"\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8\u7d00\u8981"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueNumber":"34","bibliographicPageEnd":"207","bibliographicPageStart":"197"}]},"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":"No34p197.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2002009/files/No34p197.pdf"},"version_id":"58fc4d8c-835a-4c44-a23f-a19ca7b9cdc2"}]},"item_title":"\u4e7e\u71e5\u7802\u306e\u7e70\u308a\u8fd4\u3057\u5358\u7d14\u30bb\u30f3\u65ad\u7279\u6027\u306b\u95a2\u3059\u308b\u5b9f\u9a13\u7684\u7814\u7a76","item_type_id":"15","owner":"1","path":["1642837862795","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-09-16"},"publish_date":"2007-09-16","publish_status":"0","recid":"2002009","relation_version_is_last":true,"title":["\u4e7e\u71e5\u7802\u306e\u7e70\u308a\u8fd4\u3057\u5358\u7d14\u30bb\u30f3\u65ad\u7279\u6027\u306b\u95a2\u3059\u308b\u5b9f\u9a13\u7684\u7814\u7a76"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-02-14T21:21:01.410440+00:00"}
