The degree of the curvature increases regularly with increasing preconsolidation stress (P_0) and overconsolidation ratio (n_p). In this paper the mathematical relationships that exist between the shear strength envelopes and P_0 and n_p are developed. The results are summarized as follows : 1. The peak strength (τf) may be expressed in terms of σ and n_p : ^τf=b^^^- + T. σ^n. n_p where b^^^-, T and n are constants dependent on the degree of overconsolidation and a given soil. 2. Using P_0 as a replacement for n_p, the following expression is obtained : τf=b^^^- + T. σ^<n-1>. P_0 It shows not only the fact that the value of τf is proportional to the value of P_0,but also the relationship between τf and σ for P_0=constant. 3. The constants b^^^-, T and n are therefore determined from τf&acd;n_p relationship in the limited stress range for a given soil, and then the shear strength curves for various preconsolidation stress can be illustrated.","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/20.500.12000/4371"}]},"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.
