Research paper thumbnail of Providing a New Empirical Failure Criterion for Intact Rock and Comparing it With Three Criteria Bieniawski

These factors have mostly been associated with some limitations, because of the natural complexity in rock sample’s behavior in deformation and physical form. Some of these parameters are appropriate for a specific type of rock or special condition in laboratory. By comparison with other parameters, although Bieniawski, Ramamurthy and Hoek criteria show minimal limitations, but according to this paper, they are not accurate enough in correlation with the results of the tests. In this paper a new empirical criteria is introduced and compared to the three mentioned criteria and as a result, the advantages of this newly introduced parameter in correlation with the test results are interpreted.
