Tunnel arch vertical wall displacement solution viscoelastic
+); _ √ hoop; = din + the + pan E2.3.3 Tunnel arch vertical wall displacement solution of the new solution viscoelastic equation (15) and (16), (17), (1 (19), respectively,[link widoczny dla zalogowanych], into (3),[link widoczny dla zalogowanych], may hinder the five viscoelastic arched tunnel surrounding rock vertical wall displacement solution. When the tunnel is not excavation, the initial displacement of viscoelastic stress complex function expressed as \0l () = a2 ∞ (); X02 () = a 30lI./.I (). vertical wall arch Tunnel initial stress of viscoelastic displacements as' chop Haw. one hundred and eleven EE = fI v ix How the first 6 Xue Lin. osprey arch by vertical wall surrounding viscoelastic displacement solution 101Q2Jl (t) -) 3 a Q1J2 (t)] coR (p,[link widoczny dla zalogowanych], O) tt3Qt0} (21) 0 ():[~ Q2Jl ( ) a lJ2 ()],( p,) J ... straight from the wall of the arched tunnel I imprison rock viscoelastic displacement components for the (t) =) a u0 (= Σ (P, port) ~ (just (? n2} (22) l A, v () I () a 0 (f) = 2 [.

Poynting-Th0mson exploration model and Burgers model of soft rock underground tunnel surrounding vertical wall arch Viscoelastic displacement solution. The theory of solution methods are universal in mechanics. for any non-circular shape of the orifice of the tunnel, as long as the books by the complex function mapping functions found ready-made or ready-made elastic found in books mapping function and the stress boundary conditions to determine the complex potential function is easy to obtain the deletion-type (22) in which she stresses geometric function lgi (P.),, from) and the initial stress geometric function (, shad, (P,[link widoczny dla zalogowanych], ), the author discussed in detail in another paper to determine the geometric function of the numerical stress analysis methods Ll. and all kinds of fools elastic rock medium creep compliance J (t) and generalized creep compliance J2 (f ), in this paper have been given. So from (22) can be buried in soft rock tunnel for a variety of non-circular shape from the surrounding rock excavation I Viscoelastic displacement solution.
