In this paper, in order to estimate the in situ strength of carbonate soils based on the grading of sediments, the effect of a content of gravelly component on the shear strength of carbonate sand was investigated in laboratory. A series of triaxial compression tests was carried out on the reconstituted sand with various content of gravelly component. The effect of the content of gravelly component on shear strength is significant more than that of the size of gravel. The internal friction angle at failure increases with the increase in content of gravelly component and remains to be constant over the content of gravelly component of 40%. On the other hand, the critical state friction angle shows the value of 41 degree independent of the particle size of gravel and the content of gravelly component.", "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": "琉球大学農学部"}]}, "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/20.500.12000/3646"}]}, "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": "琉球大学農学部学術報告"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
