Abstract: Connectivity of fractured rocks is generally ignored in the simulation of rocks seepage. In the paper, the conception of connectivity for fractured rocks is discussed carefully based on percolation theory. Simultaneously, analytical expression of calculating connectivity is developed. Furthermore, on the basis of statistic characteristics of fracture geometries, fracture networks are random generated by Monte-Carlo method. Combined numerical method with analytical expression of connectivity, fluid flow characteristics of fracture networks is modeled. Example shows fractured connectivity has very important effect on the fluid flow through fractured rock mass.
