Abstract:

SuFF the properties of rock mass and the soil has non definiteness. Thus choosing the number for this parameters can not show the abilities of soil and rock perfectly. One of the more used method for study the rock mass is using the RMR classifying that the internal parameters in that are divided to shells and each class has special property. Because of non definiteness in internal parameters appointment a boundary between them is difficult and giving the amount to them is impossible. Thus when the parameters are been near the boundary deciding about that is difficult that this cause to non definiteness about the RMR method. With making use of the phase selection and with defining the membership degree and phase numbers can consider this non definiteness in classifying the rocks, this paper little explain the phase selections, give the use of them in the RMR method. And using this method in appointment the ability of the GOLGOHAR are caused to appointment the geo mechanical parameter of rock mass and in the end, equivalent the walls of mine and give a high degree for the other matters
