Secondary title:	Numerical analysis of the Trojane Tunnel in the low construction area below the inhabited area with the programme PHASE2
Secondary abstract:	The diploma work presents the results of analysis of two geological cross sections of the Trojane tunnel: the cross section 80+300 in km and the cross section 80+250 in km, both located in the area near the Trojane restaurant. The numerical analysis of both geological cross sections was carried out by the finite element method with the programme Phase 2 v.6.0 using the Mohr-Coulomb's constitutive material model. At the beginning of the diploma work the tunnel Trojane is presented, the results of the actual geological-geotechnical research on the area of the tunnel are summarized, the technology for the construction of the Trojane tunnel is described, and the procedure of geotechnical measurements accompanying the construction is presented. The first part of the numerical analysis was carried out with the purpose of closely approaching the measurement deviation in the profile of 80+300. By taking into account the characteristics of soil and rock which best describe the actual deviations in the profile 80+300, the second part analysed also the profile 80+250 with a bit different geometry. The achieved results are compared with measured deviations reached by Saša Miklavžin's diploma work using the programme Plaxis.

Abstract (ePrints):	Diplomsko delo obsega numerične analize dveh geoloških profilov predora Trojane in sicer profila v km 80+300 in profila v km 80+250, ki se nahajata v območju gostišča Trojane. Numerične analize za oba geološka profila so bile izvedene po metodi končnih elementov s programom Phase2 v. 6.0. Uporabljen je bil Mohr – Coulombov konstitutivni materialni model. V uvodnem delu naloge je predstavljen predor Trojane, povzeti so rezultati izvedenih geološko-geotehničnih raziskav na območju predora, opisana je tehnologija gradnje predora Trojane in postopki geotehničnih meritev, ki so spremljale gradnjo. Prvi sklop numeričnih analiz je bil izveden z namenom čim bolje se približati izmerjenim pomikom v profilu 80+300. Z dobljenimi karakteristikami zemljin in kamnin, ki najbolj opišejo dejanske pomike v profilu 80+300, je bil v drugem sklopu analiziran še profil 80+250, ki ima nekoliko drugačno geometrijo. Dobljeni rezultati so primerjani z izmerjenimi premiki in z rezultati, dobljenimi v okviru diplomske naloge Saše Miklavžin s programom Plaxis.
