Abstract:
Namen pričujočega dela je prikazati zahtevnost in kompleksnost projektiranja predorov v slabo nosilnih hribinah. Na začetku je prikazana splošna predstavitev predorov, kjer je v zadnjem delu podrobneje opisana tudi nova avstrijska metoda predorogradnje (NATM), ki je najpogosteje uporabljena metoda za projektiranje predorov na slovenskih tleh. Za praktičen primer je v nadaljevanju izvedena 3D geotehnična analiza primarnega podporja po NATM in njihovo dimenzioniranje. Ti rezultati so nato primerjani z rezultati analize, katere smo dobili na osnovi izvedene 2D osnosimetrične analize z upoštevanjem 3D učinkov. Ker so 2D analize precej hitrejše, ter zahtevajo tudi manj sodobno računalniško opremo, je smiselno ugotoviti, za kakšne primere dobimo iz njih zadosti natančne rezultate. Na osnovi rezultatov obeh analiz so na koncu podani zaključki, ki dokazujejo, da za dani primer iz 2D analize ne dobimo zadovoljivih rezultatov. Rezultati analiz so tudi inženirsko interpretirani.

Title:
COMPARISON OF 3D AND 2D AXIALLY SYMMETRIC ANALYSIS OF THE TUNNEL IN DEMANDING GEOTECHNICAL CONDITIONS
Abstract:
The purpose of this work is to show the difficulty and complexity of the design of tunnels in poor load-bearing rocks. At the beginning is shown the overall presentation of the tunnels, where in the latter part is described in detail the new Austrian tunnelling method (NATM), which is the most commonly used method for the design of tunnel on the Slovenian territory. For a practical example 3D geotechnical analysis of the primary support units according to NATM and their design is performed. These results are then compared with the results of analyzes, which were obtained on the basis of an analysis of 2D axially symmetric taking into account the 3D effects. Since the 2D analyses is much faster and require less modern computer equipment, it makes sense to figure out what kind of examples give sufficiently accurate results. Based on the results of both analyzes at the end conclusions are made, showing that for a given example referred 2D analysis does not yield satisfactory results. Results are also interpreted in engineering way.
