Abstract

Skupaj s hitro urbanizacijo in povečano gospodarsko rastjo po svetu se povečujejo tudi zahteve po hitrejših in zanesljivejših transportnih poteh. Velik del napredka v hitrosti transporta na kopnem lahko pripišemo izgradnji predorov. Ti med seboj povezujejo mesta in pomembna gospodarska središča po najkrajših možnih poteh. To pomeni, da so inženirji odgovorni za gradnjo teh predorov, velikokrat soočeni z zahtevnimi geološkimi in gradbenimi pogoji, ki med drugim zajemajo tudi gradnjo predorov pri nizkem nadkritju. Stabilnost predora med gradnjo, ter posedki na površju, ki se kažejo kot posledica izkopa, so v primeru nizkega nadkritja zahteven del gradnje predora in pogosto predstavljajo velik inženirski izziv. V ta namen so bile razvite različne izkopne metode in ukrepi, ki se uporabljajo v gradnji predorov po vsem svetu, ter so tudi osrednji del tega diplomskega dela. Na konkretnem primeru bo predstavljena delna izgradnja severnega portala železniškega predora Pekel na relaciji Maribor–Šentilj, ki zajema različne tehnološke izzive predstavljene v tem diplomskem delu. Za konec bom ugotovitve pridobljene pri gradnji predora Pekel predstavil v obliki diskusije in zaključnih sklepov.

Secondary title:	shallow overburden tunnelling methods
Secondary abstract:	With the fast pace of global urbanization and economic growth the demand for faster and more reliable transportation routes has seen an enormous increase over the last few decades. One of the biggest parts of the progress in land transportation can easily be addressed to the increased construction of tunnels which connect cities and important economic centres via the shortest possible route. This means that the engineers responsible for the construction of these tunnels are often confronted with demanding geological and constructional conditions, which include the construction of shallow tunnels with low overburden. The instability during the construction and the surface settlements due to excavation are in the case of shallow tunnels greatly increased and they represent a great engineering challenge. For this purpose, we have seen many different tunnel excavation methods emerge worldwide, which are also the central part of this assignment. For the practical part of this assignment we will have a look at the recent construction of the north portal of the Maribor-Šentilj railway tunnel, which includes many of the difficulties discussed in this paper. Finally, we will reconsider some of the methods used in the mentioned practical case to see if the construction methods were really the best possible for the given case and if there is room for possible improvement.
