Particularly, in this investigation, the limit theorem was generalized. This generalization of the theory does not require the assumption of 'associated' flow rule. And then A method to search such admissible collapse mechanism was newly developed in this investigation. The limit analysis using this new method does not require the special technique to search the admissible collapse mechanism which is close to the exact solution. This method can form the admissible collapse mechanism without any artificial trial. The variations of bearing capacity factors with Ko are given for various types of shear test. The bearing capacities calculated by the present theory show fairly good agreement with the experimental results. The undrained strength measured by shear tests should be corrected in connection with the strength anisotropy and the effect of shear rate when they are introduced in conventional stability analysis. The correction factors for strength anisotropy are given by using present theory for various kinds of test strength., 研究課題/領域番号:63550359, 研究期間(年度):1988 – 1989, 出典:研究課題「極限解析における上・下界定理の現代的解釈と地盤の安定解析への適用」課題番号63550359 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-63550359/635503591989kenkyu_seika_hokoku_gaiyo/)を加工して作成, 金沢大学工学部}, title = {極限解析における上・下界定理の現代的解釈と地盤の安定解析への適用}, year = {1993} }
