A method for describing topological structures of rock fracture networks developed by rock fractures

摘要

Problem to be solved: to provide a method for describing topological structure of rock fracture network.The method of drawing according to one embodiment includes the step of acquiring an original position image of rocks having different deformation times using an image processing apparatus, and obtaining the spatial extent of the subpixel crack in the original position based on each image.In this solution, because of the fact that the results are different due to the difference in the form of the structural discretization, it is not necessary to simplify the image boundary condition and does not include inherent crevice information, so that the rock fracture network is effectively depicted; The whole process of the development of the rock fracture network can be obtained.Diagram
