Abstract

Tema ovog diplomskog rada je „Geotehnički projekt tunela Podmurvice“. U prvom dijelu rada obrađena su osnovna načela i principi Nove austrijske tunelske metode (NATM) prema kojoj je glavni nosivi element upravo stijenska masa, odnosno, tlo u kojem se tunel nalazi. Objašnjeni su osnovni termini vezani uz tunelogradnju te tehnologija izvedbe tunela. Nadalje, opisana je Geomehanička klasifikacija stijenske mase te su prikazane preporuke pojedine klasifikacije za određivanje primarnog podgradnog sustava ovisno o kategoriji stijenske mase. Primarni podgradni sustav sastoji se od stijenske mase, mlaznog sidara i zavarenih čeličnih mreža. U drugom dijelu rada prikazan je geotehnički proračun tunela Podmurvice koji se temelji na rezultatima istražnih radova. Numerički proračun je proveden je računalnim programom Flac 5.0. te su pomoću njega dobivene vrijednosti horizontalnih i vertikalnih pomaka tunelskog iskopa kao i sile u podgradnim elementima. Ulazni parametri čvrstoće stijenske mase dobiveni su iz računalne aplikacije RocLab.

Abstract (english)

The topic of this diploma thesis is "Geotechnical project of the Podmurvice tunnel". The first part of the paper deals with the basic principles and principles of the New Austrian Tunnel Method (NATM), according to which the main load-bearing element is the mass, ie the soil in which the tunnel is located. The basic terms related to tunnel construction and tunnel construction technology are explained. Furthermore, the Geomechanical classification of rock mass is described and the recommendations of individual classifications for determining the primary support system depending on the category of mass are presented. The primary support system consists of rock mass, shotcrete, anchors and welded steel mesh. The second part of the paper presents the geotechnical calculation the Podmurvice tunnel based on the results of exploration work. The numerical calculation was performed with the computer program Flac 5.0. and the values of horizontal and vertical displacements of the tunnel excavation as well as the forces in the support system obtained with its help. Input parameters of rock mass strength were obtained from RocLab computer applications.
