Tunneling
Tunneling
(OP)
Hello,
I am looking into a method of tunneling that is new to me. It requires the thrusting of specially developed curved metal plates at a specified length and width, into the soil, then continuing to attach each link until an arc forms and a tunnel is created, then it is excavated, with the metal arc acting as the wall supports. The tunnel can be excavated to a certain height to allow for the equipment and personnel to conduct the construction.
Does anyone have a reference for me

Do you know a reference for equations to design the plates ie. min required thickness, etc.

If you can also send me the scans to mnassif@utdinc.com.
Thanks, I tried sending this post before, but I don't think it went through, so here it is again.
