In order to accurately describe the rock fracture network flow field condition,the fracture of the intersection was taken as a node and the node between the fracture line was taken as line element by basing on the discontinuous fracture media seepage theory and fluid mechanics; the line element flow to the common node of each wire flow amount was equal to the change in storage. And then the seepage equations were established and the groundwater seepage flow model of fracture network flow media was built. And the simulation domain was calculated by using this method,and then the results with the classical numerical method were compared. The results show that the line element method model can accurately characterize the structural characteristics of fractured aqueous medium,and which is able to accurately reflect the actual groundwater flow direction.
