| Summary: | 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. |
