In general, it is difficult to explain the occurrence of a landslide with stability analysis based on the result of routine tests on an overconsolidated clay like Shimajiri mudstone, and a problem always arises in selecting the kind of strength parameters to be used. In order to approach the problem, the residual factor, R, is introduced into the c'-φ' relationship obtained by the back analysis and the failure criteria of Mohr-Coulomb, and this makes the determination of the parameters, <c'>^^^- and <φ'>^^^-, possible. This report also considers the remedial excavation (flattening and benching cut) on the landslide and indicates, from the investigation into the relation between the quantity of excavation and satety factor resulting from stability analysis based on the parameters, <c'>^^^- and <φ'>^^^-, that benching of the slope becomes clear to be more available than flattening. Benching work, however, has a close connection with the satety of a slope and a structure located to the upper part of the troubled area. Consequently, a method to effectively combine the both excavations should be used at the present time, together with buttress, counterweight fills and so on.","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/20.500.12000/4104"}]},"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.
