渗流

By means of FEM simulation and application of the equivalent continuum model and the discrete fissure model, we can conclude that the larger density of fissure, the more identical the two methods will be. Based on this conclusion and characteristic of fissured rocks, a new model called the entity mixed model is suggested. Many examples given in the thesis demonstrate the reliability, effectivity and efficiency of this model.
