  The role of temporary support in the design of the final lining

  Abstract: Tunnel final lining is often designed to fully undertake all loads during tunnel service life, such as loads from the surrounding ground, water pressure, live, accidental and seismic loads, while neglecting any contribution of the temporary support. The role of the temporary support measures in the final lining loading and design, even if they are finally...

  Tunnelling in Weak Rock Mass with Overlying Competent Stratum

  Abstract: Convergence in the case of tunnelling through alternations of competent and incompetent rock masses may depend on the geometrical and geotechnical characteristics of both members. In case the thickness of layers is small compared with the characteristic dimensions of the tunnel section (e.g. diameter), simulation of all layers is impractical. In this case, simulation of the heterogeneous...
