Today the rock failure criteria have a wide range of usage for determining the stress conditions around underground structures and slope stability methods .In this study we examine nine different failure criteria by comparing them to published polyaxial test data (σ σ σ 1 2 3 > > ) for five different rock types at a variety of stress states. several article have published about this subject with different criteria and rock data currently. For this purpose we need a factor named Least Mean Standard Deviation Misfits. In this paper we used all of them and try to gather them and present general result. Result of this article shows that polyaxial criteria has more accuracy.
