  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...

  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...
