Stochastic inversion of fracture networks for rock masses in fault zone and its applications
Abstract：The fracture networks of rock masses in the fault zone were statistically analyzed,which was limited quantity and measured.Statistical models of stochastic probability were built,that was dip of fracture,dip angle,trace length,gap length,and space length.On this basis,the fracture network system of rock masses was simulated by the Monte Carlo method.After that fracture network model was obtained to obey the distribution rules of Gaussian and negative exponential.The calculating results of the example reflect that fracture networks of rock masses in the fault zone are highly permeable,more than 80% structural surfaces are mutual connected and three permeable directions are dominant,that is NE,NW,approximately EW.
