dc.description.abstractIn the analysis of tunnel lining - rock mass interaction, it is essential to consider partial stress release at the tunnel face, i.e. deformation of the tunnel walling that occurs before the application of the lining. Accordingly, it is important to develop an adequate numerical model considering tunneling face effects as well as construction sequence effects. Consequently, a 3D numerical modelling is necessary. Through the use of finite element method (FEM), a numerical model is developed enabling analysis of stress-strain states considering specific rock mass properties and consequent stages of a tunnel construction. In this first paper, some elements of FEM modeling of rock mass and tunneling were introduced. 3D numerical modelling of tunnel driving process is described: treatment of construction stages, and iterative procedure for simulating the tunneling face advancement. .en
dc.description.abstractKod razmatranja problema interakcije tunelske obloge i stenske mase od suštinskog značaja je razmatranje delimične relaksacije stenske mase, odnosno pomeranja konture iskopa koja su se desila na čelu tunela pre postavljanja obloge. U tom smislu izuzetno je značajno definisanje adekvatnog numeričkog modela. 3D numeričko modeliranje neophodno je za razmatranje efekata na radnom čelu tunela kao i efekata sekvencijalne izgradnje tunela. Metodom konačnih elemenata razvija se model sa kojim se može sprovesti naponsko-deformacijska analiza po fazama građenja sa uzimanjem u obzir odgovarajućih svojstava stenske mase. U ovom prvom radu se razmatraju neki problemi modeliranja stenske mase i tunela metodom konačnih elemenata. Prikazano je 3D numeričko modeliranje izgradnje tunela pri čemu je analiziran tretman faza građenja i izložen iterativni postupak za simulaciju napredovanja čela tunela. .sr
