A STUDY OF STRENGTH CRITERION IN POWER FUNCTION FOR ROCK MATERIAL
幂函数型岩石强度准则研究

Based on the testing results of uniaxial compression test, triaxial compression test and Brazilian test for 55 kinds of rock materials within Changsha Research Institute of Mining and Metallurgy, a strength criterion in power function for rock material is obtained in this paper. The comparison of testing results with the power function criterion is satisfactory.
