| Abstract: | According to the geostatistical results of joint geometrical characteristics, a joint network was generated by means of Monte-Carlo method. Analysing the joints and their interconnection, a general equation was derived for equivalent permeability of a complex connected joint network system. In this paper the three-dimensional joint network simulation and the deformability of rock masses are discussed and the constituive relation of rock masses established. The results show that the elastic compliance coefficent matrix is a function of joint orientations, sizes and densities of joints, Youny's modulus and poisson's ratio of intact rock, and that the irregular distribution of joints orientation is responsible for the anisotropy of rock masses. |
