Abstract

Kako je tema rada „Osiguranje iskopa tunela u kršu“ u radu je za početak opisana tunelogradnja odnosno načini izvedbe, iskopa i osiguranja tunela u vidu podgradnog sustava kao i mjerenje u tunelogradnji. Također su opisane stijene u Hrvatskoj s naglaskom na stijene koje pripadaju kršu Hrvatske. Prikazuje se određivanje modula deformacije odnosno krutosti karbonatnih stijena u kršu Hrvatske, koji je osigurao pouzdaniju procjenu deformacija geotehničkih konstrukcija, u ovom slučaju tunela, koje se izvode na tom području. U konačnici, provedena je provjera utjecaja promjene krutosti po dubini na deformacije oko iskopa tunela, na primjeru tunela Bobova. Modeliranje tunela provedeno je korištenjem programa RocScience – RS2, a promjena krutosti prikazana je primjenom različite uslojenosti.

Abstract (english)

As the topic of the paper is "Stabilization of tunnels excavated in karst", the paper initially describes tunnel construction, i.e. the methods of execution, excavation and securing of tunnels in the form of an support system, as well as measurement in tunnel construction. The rocks in Croatia are also described, with an emphasis on the rocks that belong to the karst of Croatia. The determination of the modulus of deformation or stiffness of carbonate rocks in the karst of Croatia is shown, which ensured a more reliable assessment of the deformations of geotechnical structures, in this case tunnels, which are constructed in that area. Finally, the influence of the change in stiffness by depth on the deformations around the tunnel excavation was checked, using the example of the Bobova tunnel. The modeling of the tunnel was carried out using the RocScience - RS2 program, and the change in stiffness was shown by applying different layering.
