Again, take a moment to call the tunnel authority, and they can
explain to you much better than I can.  They can tell you just how
thick those walls are, with the thickness of the actual walls, 
rock, dirt, etc.  They might be able to explain to you the 
engineering standards used, and how force works against equal, or
higher opposing forces.

They could also explain just what kind of ventilation equipment is in
use.  Heck, they might even offer you a tour for your class.  In fact,
you would most likely be amazed just how a tunnel is actually put
together, and all the behind the scenes things that goes on there!
