Description (Dublin Core)

hrv Predviđanje odziva stijenskog masiva prilikom proboja tunela složen je inženjerski problem. Pri projektiranju važno je ocjenjivanje uvjeta stabilnosti iskopa, te nakon usvajanja prikladnih metoda probijanja, usvajanje odgovarajućih mjera podgrađivanja u svrhu stabilizacije otvora.Nova austrijska tunelska metoda (NATM) je metoda iskopa prilagodljiva čestim promjenama geoloških i geotehničkih uvjeta na čelu iskopa. Osim iskopa cijelog profila, iskopi u slabim materijalima duž trase tunela uvjetuju tzv. razradu profila tj. primjenu višefaznog iskopa. U radu je dana usporedba stanja naprezanja i deformacija za punoprofilni iskop sa stanjem naprezanja i deformacija pri razradi profila tj. za početne faze višefaznih iskopa NATM.
eng Foreseeing of the rock massif behaviour in tunnel breaking out is a complex engineering problem. In projecting it is important to evaluate the stability conditions in excavation and after the acceptance of suitable breaking out methods, the acceptance of supporting in order to stabilize the opening. The New Austrian Tunnel Method (NATM) is the excavation method adaptable to frequent changes of geological and geotechnical conditions at the working face. Beside the excavation of the whole profile, excavations in soft materials along the tunnel trace condition, so called profile development, i. e. the application of multi-phase excavation. The conditions of stresses and strains for the whole-profile excavation are compared with the conditions of stresses and strains for starting stages of multi-phase excavations with the New Austrian Tunnel Method.
