Most of slope failures occur controlled by the strike of geological weak planes. The shear strength along weak planes is lowered to the value close to residual strength. The peak strength is mobilized in shear zones where weak plane does not exist. Peak strength parameters for strongly weathered rock from Makiya and for weathered soil from Ue-arakawa were c_f=16.1kPa, φ_f=43.5°, and c_f=12.0kPa, φ_f=28.5°, respectively. Residual strength parameters were c_r=0kPa, φ_r=26.0∿33.3°for Makiya, and c_r=0kPa, φ_r=27.0°for Ue-arakawa, both higher than those for landslide soils.","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/20.500.12000/3689"}]},"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.
