106 Abstract one of the important problem in better understand of Slope stability Foundationdams Underground excavations Geothermal reservoirs Evaluation of pollutants Oilreservoirs and Nuclear waste disposal areas is simulation of rock mass fracture Theoretical Studies has been demonstrated the result of three dimensional modellingdiscrete fracture network is closer to reality than other models There are differentmethodes to choose the parameters of fracture network for modeling In general thereare two methods for choosing the parameters Statistics and Geostatistics In statisticsmethods there aren t any information about the position of components and samplestaken in space of the whole society As a result will not be the measured values of aspecific quantity in a particular instance no information about value of same quantity atto a certain distance another case In other words in statistical methods fracture networkmodeling generated without Spatial correlation structures randomly and by MonteCarlo algorithm Code GFracIUT Has been developed in order to three dimensionalmodelling discrete fracture network to geostatistical approach This program thenproduces microfractures to geostatistical approach checks Intersection or lack ofintersection them together After that eliminate subcritical microfractures This code iscapable of generate and display discrete fracture network for dimensions and realizationdifferent with the distinction between categories of fractures This program also arecapable of fractures modeling with different geometric shapes Including disc Parallelogram and generally polygon This code in order to modelling fluid transmitternetwork in three dimensional space on the basis size area and fractures geometricshape calculated the intersection of any fracture with other fractures or boundaries ofthe study area Then using depth first search algorithm eliminates the clusters offractures that have no connection with border or with only one the border are linked Therefore identified network of fractures that effective on the transmission network andmodeled are transmission network based on the model of the pipe network Finally using the discrete element method calculates the flow rate and conductivity of anyfracture Now by identification flow rate of any fracture be calculated output flow fromany side and permeability in each direction Keywords 1 Geostatistics 2 Discrete fracture network 3 Depth first searchalgorithm 4 Network equivalent pipes 5 Flow modeling 6 Permeability
