In this paper in order to investigate the effects of the particle breakage on the compressibility and creep deformation of coral sand, the one-dimensional compression tests up to a vertical stress of 62.72MPa and the one-dimensional creep tests under a constant vertical stress of 11.76MPa. The materials used are coral sands obtained from eight different locations in coral reefs around Ryukyus Islands, south west part of Japan. The compressibility of sand is controlled by the particle breakage. The degree of particle breakage is uniquely related to the ratio of the compressive yield stress to the maximum applied stress. Creep deformation is significant after an elapsed loading time of 1000 minutes. The time dependence of the compressibility is caused by the abrasion on the particle surface because of the increase in the percent finer than 0.075mm during creep process.", "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\u8fb2\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/20.500.12000/3667"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
