| To estimate pure shear strength, 150 sets of triaxial test data were analyzed. The proportional coefficient of shear strength($I_c$) at zero normal stress was nonlinearly decreased as failure coefficient m increases, while the internal friction $phi_0$ at zero normal stress was nonlinearly increased. The ratio of shear strength $(c/phi_0)$was inversely proportional to the ratio of the internal friction angles$(phi/phi_0)$ The shear strength decreased as m increased, while internal friction angle increased. And uniaxial strength was proportional to $c,phi$ Regression analysis showed that shear strength strongly affects m and $sigma_c$ The proportional coefficient of shear strength was nonlinearly increased with RMR, while the internal friction angle $(phi}$was linearly decreased. |
