Abstract
It isgenerallyrecognizedthattheexistenceofunknowndis-
continuities withvaryingsizes,locationsandorientationsleadtoa
significant levelofuncertaintyinthephysicalbehavioroffrac-
tured rockmasses.Uncertaintyandvariabilityarecausedbythe
nature andunpredictablebehaviorsofthefracturedrockmassas
an inherentlyheterogeneousgeologicalmaterial.Therefore,the
variabilityofthefracturedrockpropertiesisanimportantand
inescapable issue,whichremainsoneofthemostdifficult chal-
lenges. Inthisregard,stochasticanalysisofstrengthanddeform-
ability parametersoffracturedrocksisakeyissueofsitechar-
acterizationofrockengineeringprojects,whichmayprovidemore

representationofuncertainty/variabilityofthehostrockmass
concerned, andthereforeenhancingdesignofsurfaceandsub-
surface structuresinandonrockmasses,andreliableeconomic
