A tunnel is an underground passageway, dug through
the surrounding soil/earth/rock and enclosed except for entrance and exit,
commonly at each end. A pipeline is not a tunnel, though some recent tunnels have
used immersed tube construction techniques rather than traditional tunnel boring
methods.
Therefore necessary to select the optimum research method for
tunnel management, because of the increase in construction period and
construction cost that may be generated.
In this study, we propose a more advanced tunnelling
information-oriented construction technique, which effectively utilizes all the
geological and geotechnical information necessary for the construction.
For projects of that scale the quality and safety planning
required are rated of high priority.
However, it is difficult to determine the ground conditions
at the required accuracy from primary geological surveys, especially when the
project is a deep underground structure, which spans along an extensive area,
and encounters complex geological structures.
It is important to predict the likely geological conditions ahead
of the tunnel face.
Various techniques are available to assist in these kinds of
predictions.
When the survey results are being utilized, the accuracy and
reliability of the investigations must be evaluated sufficiently,
