%X Based on the principle of Mahalanobis distance discriminant analysis,a classification model of engineering quality of rock masses is established,including six indexes reflecting the engineering quality of rock masses:uniaxial compressive strength,P-wave velocity in rock,volumetric joint countr,oughness coefficients of joints,weathering coefficients and permeability coefficient of joints.Linear discriminant functions are obtained through training a large set of expansive samples.The results show that the classification model of distance discriminant analysis has excellent performance,high prediction accuracy;and can be used in practical engineering.
