Water Flow Characteristics in Fractured Rock Based on Fractal Network Model

A permeability parameter estimation methed for fractured rock is developed based on the fractal network approach. The fractal network model of fractured rock is generated as a lattice structure. The equivalent permeability of fracture network in rock masses is estimated by using parallel principle of flow network. The study investigates the influence of fractal parameters of fracture networks on permeability. The investigation show that the equivalent permeability of fractal network system in rock masses will increase as increasing scaling factor ( and number of divide Ns. It is confirmed that the permeability performance of fractured rock can be analytically predicted by using fractal network model.
