Estimation of deformation and stiffness of fractures close to tunnels using data from single-hole hydraulic testing and grouting [electronic resource]
Sealing of tunnels in fractured rocks is commonly performed by pre- or post-excavation grouting. The grouting boreholes are frequently drilled close to the tunnel wall, an area where rock stresses can be low and fractures can more easily open up during grout pressurization. In this paper we suggest...
