Settlements Upon Soft-Ground Tunneling: Theoretical Solution

D. Resendiz / M. P. Romo

A theoretical solution is presented for the settlements induced at any depth by tunneling in soft ground. The results are much more general, yet simpler, than those in current use; they are expressed in terms of parameters directly associated to the excavation procedure. The solution accounts for the effects of stress release at the tunnel face and radial soil displacement around the tunnel. The following variables are explicity included: initial state of stress, stress-strain and strength properties of the soil, depth and diameter of the tunnel, fluid pressure on the face of the excavation, and amount of radial soil yielding around the tunnel.
