英文摘要Study of intact rock failure criteria is an important topic in rock mechanics. In this study, applicability of nine different intact rock failure criteria is investigated for intact coal strength data. PFC3D modeling was used to simulate the laboratory polyaxial tests for cubic intact coal blocks of side dimension 110 mm under different confining stress combinations. A modified grid search procedure is proposed and used to find the best-fitting parameter values and to calculate the coefficient of determination (R (2)) values for each criterion. Detailed comparisons of the nine criteria are made using the following aspects: R (2) values, sigma (1) - sigma (2) plots for different sigma (3), shapes on the deviatoric plane, linearity or nonlinearity on the meridian planes. Through the comparisons of R (2) values, sigma (1) - sigma (2) plots and meridian lines, the modified Wiebols-Cook and modified Lade criteria were found to fit the intact coal strength data best. The nine failure criteria are categorized into three types based on the appearances on the deviatoric plane.
