摘要
本文针对节理岩体进行了二维与三维节理网络模拟研究。基于随机节理网络系统的连通性分析,得出了复杂连通节理网络系统的岩体等效渗透系数的一般表达式。同时,利用三维节理网络模拟,建立了包含随机非贯穿节理的节理网络系统的岩体本构关系,并分析了影响岩体弹性变形性状的因素。
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.
