Numerical characterization of groundwater flow and fracture-induced water inrush in tunnels

Recently, the rapid increase in tunnel construction in karst areas across China has attracted considerable attention. However, frequently occurring groundwater inrush hazards induced by fractures within rocks are one of the greatest challenges faced during tunnel excavations. In this paper, we present a numerical investigation on the effect of fractures on fluid flow, considering the different types of discontinuities. A conceptual model of...
