When the slips are analysed using the peak strength parameters, the calculated factor of safety is F_S=7\u0026acd;11. 2. The estimated value of effective cohesion is c\u0027^^^-=0\u0026acd;0.130kg/(cm)^2. This value is obtained from the c\u0027-tan\u03c6\u0027 diagrams made by the stability analysis of five landslides, using \u03c6\u0027^^^-=15\u0026acd;20\u00b0obtained from the present shear test. 3. According to the stability analysis of the slope after sliding and that of the original slope, results obtained from the Takara landslide show as follows : The factor of safety is 10.9 for the slope after sliding and 7.8 for the original slope when the peak strength is applied to the stability analysis. On the other hand the factor of safety is 0.6 for the slope after sliding and 0.29 for the original slope when the residual strength is applied. Since the correct factor of safety is 1.0 at the failure, the residual factor R=0.94 corresponding to the factor (of safety) gives c\u0027^^^-=0.072kg/(cm)^2 and \u03c6\u0027^^^-=17.2\u00b0for the slope after sliding. The value R=0.91 for the original slope gives c\u0027^^^-=0.113kg/(cm)^2 and \u03c6\u0027^^^-=17.3\u00b0. As mentioned above, the analysis of the forces acting on the slip surface shows that average shear strength is rather close to the residual and fully-softened strength than the peak strength. Therefore, it is necessary to analyse the stability of natural slopes in softened Shimajiri mudstone by using the mechanism of progressive failure, and residual and fully-softened strength.", "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/20.500.12000/4204"}]}, "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.
