Abstract：The development degree of joints in rockmass is a significant factor affecting rockmass structure types，rockmass quality and comprehensive utilization of engineering rockmass，and it is important to estimate quantitatively the development degree of joints in rockmass. After introducing the classification of rockmass joints，the joint number per unit area which is equivalent to the joint number on the cave wall per 5 m is chosen as quantification index of the development degree of joints in rockmass. Then，in a hydropower station which will be built on Yellow River，the joint number per unit area is analyzed carefully by means of mathematical statistics，and then the relation between development degree of joints and deformation parameter of rockmass is studied. The presented study provides a theory basis for rockmass evaluation.
