Submitted to ”geotechnik”... Time-dependent behaviour of shotcrete lining was considered in 3D simulations, whereas constant final stiffness was used in the plane strain analyses....
Numerical analysis of 3-d flac on supporting effects of underground caverns surrounding rockmass... Then, the paper gives the computational results of rock deformation and stability for the large cavern group and comparisons for three cases: with no supporting structures; with bolts and shotcrete lining but no prestress-cables and with all the supporting structures of bolts, cables and lining....
Roughness evaluation in shotcrete-lined water tunnels with invert concrete based on cases from nepal... With the improvement in shotcrete technology, advancement in tunneling equipment and cost and time effectiveness, future water tunnels built for hydropower projects will consist of rock support with the extensive use of shotcrete lining in combination with systematic bolting and concrete lining in the tunnel invert....
Computation of primary tunnel support... In this paper, the stress and strain conditions for a tunnel profile excavation are compared with the stress and strain conditions for shotcrete lining supported excavation profile....
