     a comparative study was carried out on tbm average rate of advance (ara) predicted from conventional rock mass excavability (rme) index and fuzzy modeling using a database developed in mostly hard to very hard volcanic rocks in gilgel gibe ii headrace tbm driven tunnel in ethiopia. comparison of measured aras with those predicted by the fuzzy model showed a good agreement with correlation coefficients of 0.87 which is more than 0.75 that achieved for conventional rme classification system. this highlights the potential of fuzzy rock mass classifications as a more promising tool in tbm performance prediction compared to conventional rock mass classification systems.
