An index based on fracture length and aperture to predict groundwater inflow rates in tunnels excavated in fractured-rock
The surface area of the fractures at the wall of a tunnel is used to develop a representative
index, as inflow index, for the prediction and the classification of the inflow rate to a tunnel …
