構造物設計における材料のせん断強度の表現法について

抄録

Mohr's envelopes, which describe the shear strength of materials, are shown for structural designs, particularly the stability analyses of rockfill dams. Firstly, an effective method which has passed into oblivion is followed by a complete verification. This method provides a general analytic solution for Mohr's envelopes and is applicable to arbitrary functions which describe the results of triaxial tests. Then, the method is applied to a particular empirical criterion for rockfill materials which has been recommended over a long period of time. Suitable results are obtained from the application of such a method to a set of triaxial data for a particular rockfill material.
