CONSTRUCTION OF THREE-DIMENSIONAL PORE NETWORK IN BULK GRAIN

摘要：

　　In order to construct 3D pore network reflecting real pore structure of bulk grain,a series of 2D section images are obtained and used to reconstruct 3D images by MATLAB.The parameters of 3D pore network are extracted by the maximal ball method.A stochastic 3D pore network with random size is generated,but some throats lost in generation.The parameter deviation between original model and generated model decreases with the volume increases.There is almost no deviation when the space size is up to meter level.The image resolution of 0.5mm is enough for extracting parameters of bulk grain.
