Based on the ridge function derived from Matsuoka-Nakai,Lade-Duncan and Ottosen strength failure criteria,a modified Ottosen failure criterion is proposed and verified by the true triaxial strength test data of concrete and rock.

- 基于從Matsuoka-Nakai；Lade-Duncan和Ottosen等強度破壞準則導出的角隅函數；提出了修正的Ottosen強度破壞準則表達式；并通過(guò)混凝土和巖石的真三軸強度破壞試驗結果進(jìn)行驗證.
