Hydrogeological approaches is applied to characterize a site of a shaft for a highway tunnel. More than 3400 fracture data acquired to establish a model that characterizes fractured rock mass. Permeability tensor of rock and potential flowing paths of groundwater to the shaft is determined. Two plans for mitigating water inrush during shaft construction are proposed accordingly.
