Tunnel/soil interaction
Tunnel/soil interaction
(OP)
I need a way of modeling the tunnel liner/soil interaction in RISA 2D. I have referenced the Army Corps of Eng. "Tunnels and Shafts in Rock" EM1110-2-2901, May 97, section 9-10 and found several formulas regarding tangential and radial spring stiffness calcs. I think this is the dreaded, so-called "modulus" of subgrade reaction, however. Does anyone have any experience/advice in modeling tunnels? Helpful hints? Pitfalls to avoid?
Thanks in advance if you do.

I have a very good source for tunnel design, but it can be difficult to obtain:
"Geotechnical Engineering Investigation Manual", Hunt, Roy E., McGraw Hill, 1983: isdn 0-07031309-1
Give this source a try. I have not used RISA 2D so I can't help you there.

However there is specific 2D and 3D software for buried structures and if available some will do better than the -for this purpose- non targeted RISA 2D.
So I would do some internet searching for available programs.
