Seepage through fractures in geologic body is a very complex problem. Usually, its macro-seepage characteristic can be described by the equivalent permeability tensor. Based on the superposition algorithm for calculating the equivalent permeability tensor of multiple sets of infinity parallel fractures, this paper developed a kind of more general superposition algorithm by introducing a concept of the through coefficient of fracture. Combining with computer-generated technology of random fracture network, the method can be used to approximately estimate the equivalent permeability tensor of two-dimensional random fractures.
