Abstract
S obzirom da trenutno ne postoje evropski standardi za projektovanje tunela, u praksi se sve više koristi Evrokod 7, naročito za projektovanje plitkih tunela u tlu. Pri projektovanju tunela, da bi se adekvatno predvidelo ponašanja složenog interaktivnog sistema obloga-tlo, neophodna je primena naprednih numeričkih metoda. Numeričke metode se u praksi primarno koriste za analizu pomeranja usled izgradnje tunela, odnosno graničnih stanja upotrebljivosti. Međutim, rezultati numeričkih analiza se sve više koriste i za provere graničnih stanja loma u konstrukciji i terenu kod projektovanja tunela. U radu je dat pregled postupaka primene projektnih pristupa definisanih u Evrokodu 7 u projektovanju tunela primenom naprednih numeričkih metoda.
Given that there are currently no European standards for tunnel design, Eurocode 7 is increasingly used in practice, especially for the design of shallow tunnels in soft ground. When designing tunnels, in order to adequately predict the behaviour of a complex interactive lining-ground system, it is necessary to apply advanced numerical methods. Numerical methods are used in practice primarily for the analysis of displacements induced by tunnelling, i.e. serviceability limit states. However, the results of numerical analyses are increasingly used for ultimate limit state design of tunnels. The paper gives an overview of the procedures for applying the design approaches defined in Eurocode 7 in tunnel design using advanced numerical methods.
