<p>This section summarizes some local tunneling projects constructed in geologic conditions similar to the various zones being considered for the SR-710 Tunnel. These local projects include the NEIS, the ECIS, and the Metro Red Line and Gold Line Eastside ...

<p>In shield tunneling, the excavation stability is very important. The balance pressure which supports the work face is offered by the the mucks in the earth chamber. The ideal supporting pressure on the excavation face is trapezoidal. In fact, the pressure ...

<p>The focus of this paper is too list the required information for the design of a TBM and focus on the selection of the EPB or Slurry TBM method of face support based on the conditions of the project, from geology, alignment restrictions and local knowledge ...
