Abstract: Compute modeling for 3D-fracture network of hock mass is an important application of modem computer technique in nxk mechanics. Field data of rock fractures gotten in holes or on outcrops only possess 1D or 2D distribution characters, and often contain sampling error.So many kinds of corrections must be made before the data being used to determine distribution parameters of 3D-fracture with stereology. The source data of 3D-fracture network are devel-oiled from distribution parameters of 3D-fracture with Monte Carlo Method, and the visual display of the network can be implemented using Visual C++combined with Open GL technique. The up-to-date research of correction meth-ods for measuring data of hock fracture is reviewed in this paper, and the implementation of a 3D-fracture model for a practical project is displayed in order to illustrate the press of 3D-fracture network modeling.
