“…The monitoring data can simply provide information about the tunnelling conditions [3], or may be used in the back analyses to model the soil behaviour and to design the tunnel lining by comparing measurements to the computed behaviour [4][5][6][7]. Alternatively, Vardakos and Gutierrez [8] process the convergence measurements with a statistical framework based on the Markov estimator to calibrate the analytical or numerical models.…”

SUMMARYFoliated rocks such as micaceous schists are particularly prone to anisotropic creep. This fact may cause severe problems of squeezing when driving deep tunnels, especially when the tunnel axis is not perpendicular to the foliation planes. A rational approach to the prediction and assessment of squeezing as a process in time and, therefore, also pertinent experimental results are still missing.Starting from a simple approach to anisotropic creep/relaxation we show its implications for tunnelling by means of numerical simulations.

“…They may also need complex calibration procedures (Guan et al, 2009) that, in addition, are based on convergence data that is only available after tunnel construction (Zhifa et al, 2001;Boidy et al, 2002). This aspect, in conjunction with the complexity of the models involved, greatly reduces the a-priori capabilities for squeezing prediction of such methods and, in addition, it makes their application difficult prior to tunnel construction and reducing their usefulness during the planning stage.…”
