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 reliable estimationofvariabilityofstrengthanddeformabilityof the fracturedrockmassesconcerned,asameansofquantitative representationofuncertainty/variabilityofthehostrockmass concerned, andthereforeenhancingdesignofsurfaceandsub- surface structuresinandonrockmasses,andreliableeconomic evaluation.
