Numerical Study on the Resistivity Tomography Applicable to TBM
Abstract: Various kinds of geological surveys, such as drillings, geological mapping, and geophysical surveys, are generally conducted to clarify the ground condition of the proposed tunnel route and/or the existence of anomalies to allow proper design of the tunnel. The geological survey performed in the design step mostly focuses on estimating the overall ground condition or underground geological...

Risk Analysis Applicable to Shield TBM Tunnels
Abstract: In this paper, the potential risk of undesirable events that may occur during tunnelling work with a Shield TBM method is discussed along with the general risk analysis that can systematically assess overall risk levels. Potential risks and typical scenarios pertaining to shield TBM tunnels have been investigated based on previous case histories and correspondence with experts. The relevant...

Risk Analysis using Bayesian Networks Applicable to Shield TBM Tunnels
Abstract: The tunnel boring machine (TBM) system, the most representative mechanized tunneling method, has been widely adopted in numerous tunneling projects. It is also quite environmentally friendly, exhibiting minimized noise and vibration when compared with conventional tunneling methods. Moreover, it provides considerable economic benefits that allow for high advance rate for long drives during...
