Harmony Search Algorithm to Predict Anomalous Zone Ahead of Tunnel Face
Abstract: During tunnelling work, emergence of unpredicted fault or anomalous zone leads to delay of construction work or increase of construction cost hampering construction ability. Predicting the anomalous zone ahead of tunnel face in advance can thus prevent time and economic loss. This raised the demand to develop a prediction technique that detects anomalous zones ahead of a tunnel face during...

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 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...
