A New Method to Three-dimensional Dual Medium Geometry Model Construction

Abstract Dual medium geometric model is widely used in soil and rock mass environment, which can only reflect the material exchange between cracks matrix. The dual ignores hydraulic relationship pores cracks. paper develops a new method to construct three-dimensional geometry model. This completely written by Matlab scripting language, describe real spatial distribution state of fracture bedrock. In method, random network models with different parameters porous media Berlin Noise characteristics are constructed respectively, then use direct superposition introduces construction model, method. research great significance numerical simulation related fields.
