Abstract
Projektiranje tunela se kroz vrijeme olakšalo razvitkom numeričkih programa koji se baziraju na metodi konačnih elemenata. U ovome radu provedena je analiza četiri poprečna profila Tunela Podmurvice u numeričkom programu RS2 te su dobiveni iznosi faktora čvrstoće stijenske mase, ukupni pomaci, momenti savijanja mlaznog betona, normalne i poprečne sile u mlaznom betonu te osne sile u sidrima. Odabran je najkritičniji presjek te je provedena parametarska analiza varirajući iznose modula elastičnosti stijenske mase te visine nadsloja. Time su dobivene krivulje ovisnosti pomaka u stijeni i na kaloti tunela o modulu elastičnosti za svaki pojedini nadsloj. Ustanovljeno je da za su male iznose modula elastičnosti pomaci veći te se povećavanjem modula smanjuju. Dobiveni su i iznosi većeg i manjeg glavnog naprezanja.
Abstract (english)
Over time, tunnel design has become easier with development of numerical programs based on the finite element method. In this paper, an analysis of four transverse profiles of the Podmurvice Tunnel was carried out in the numerical program RS2, and values of the strength factor of the rock mass, total displacements, bending moments of shotcrete, normal and shear forces in shotcrete and axial forces in anchors were obtained. The most critical cross-section was selected and a parametric analysis was carried out by varying the amounts of modulus of elasticity of the rock mass and height of the overlying layer. In this way, the dependence curves of displacement in the rock, and in the top of the tunnel, for each individual layer were obtained. It was found that for small values of the modulus of elasticity, the displacements are larger and decrease as the modulus increases. The values of major and minor principal stresses were also obtained.
