Based on the research work on generation and visualization of three-dimensional stochastic fracture network simulation,a new three-dimensional stochastic fracture network model is established.It is assumed that the fracture shape of the model is a Baecher disc,the distribution is stochastic,and the correlativity of dimension,location,orientation and aperture of all fractures is independent.Based on these,a sample element of a three-dimensional structural plane network is generated separately by Poisson stochastic process.The spatial geometrical intersection information of the fractures and the boundary sides is discussed in detail.As a result,a program named FRCGEN-3D for three-dimensional stochastic fracture network of flow is developed by the FORTRAN90.To visualize the three-dimensional network model and check the data conveniently,a new specialized visualization system called V-FNW is developed with OPEN GL tools in Visual C ,which is powerful and famous for graph process.The system V-FNW shows interactive interface with three-dimensional graph rendering,rotation and intersection.Finally,an example of a stochastic model with a set of specific data is given;and the result is reasonable.It provides a visual platform of fracture network simulation for rock mechanics and rock hydromechanics,which is very important and valuable in the further research.
