Abstract

Water inflow inside underground structures causes numerous problems during their construction and continuing operation, which means that engineers need to control inundation to optimize operational activities. Discontinuities in a rock mass, including joints, bedding planes and foliations, combine to form a discontinuous mass. When fluid passes through such a medium the flow becomes heterogeneous. Because these discontinuities act as channels, flow through the rock mass is controlled by the location, orientation, and characteristics of individual discontinuities or discontinuity sets
