To eliminate the effect of the skin friction on normal stress on shear surface, the conventional Mikasa\u0027s direct shear apparatus is improved to be able to measure the normal stress on shear surface. In this paper, to investigate the effect of the skin friction on the shear strength, constant pressure tests and constant volume tests are carried out on sands using the improved direct shear apparatus. Test results show that the skin friction between specimen and shear box wall influences the shear strength obtained from a conventional direct shear apparatus. It is necessary to determine the shear strength with normal stress on shear surface in both a constant pressure test and a constant volume test. The shear strength obtained from constant pressure test using the improved direct shear apparatus is consistent to those of the triaxial compression test.", "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/20.500.12000/3603"}]}, "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.
