  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...
