This study is concerned of the physical and mechanical properties of granite at Doon-Nae in Gang-Won. Uniaxial compressive strength, tensile strength, triaxial compressive strength, unit weight, absorption and shore hardness were measuerd. Elastic modulus and poission's ratio of rock were obtained by stress-strain curves through uniaxial compressive test and cohesion and friction angle were obtained by Mohr-Coulomb theory. Factor anlaysis was performed for the physical and mechanical properties and the correlation matrix was analysed for each factors. As a result of factor analysis, Multiple regression for the dependent factor was performed from the several independent factors.
