The purpose of this study is to present an algorithm for tunnel and portal support design in weak rock conditions. Basic principles of engineering design are introduced and the main stages of the design process are delineated through assessing a highway tunnel case study in Turkey. This case study involved the investigation of the engineering geological and geotechnical characteristics of the rock material and rock mass of the tunnel grounds; evaluation of the field stresses, the applied loads and the deformations around the underground excavations; assessment of the validity of decision making (i.e., alternative selection); and finally, suggesting appropriate support and stabilization techniques for optimum tunnel design.

Portal slope stability assessment of a proposed highway tunnel in northeastern Turkey
Sopaci, E.; Akgün, Haluk (2009-01-01)
This paper presents an application of the rock mass classification systems, namely, Geomechanics Classification System (RMR), Geological Strength Index (GSI) and the newly adapted A-RMR for the characterization of the rock masses surrounding the portals of the Ordu Peripheral Highway Tunnel. In order to characterize the rock masses, which mainly consist of flysch (mostly alternation of sandstone, marl and siltstone) and pyroclastics (agglomerate and tuff), engineering geological investigations have been car...
Geotechnical investigations and preliminary support design for the Gecilmez tunnel: A case study along the Black Sea coastal highway, Giresun, northern Turkey
Akgün, Haluk; Kockar, Mustafa Kerem (2014-02-01)
This study encompasses geotechnical investigations, stability assessments and design of the preliminary support systems for the Gecilmez tunnel which is constructed in Giresun for the improvement of the highway along the Black Sea coast. During the study, a detailed geological map of the study area was prepared and the geotechnical characteristics of the rock masses were determined. The rock mass classification of the tunnel grounds was performed by utilizing the RMR method, Q system, NATM and the Geologica...
On the assessment of the effect of the anisotropy in in-situ stress on support pressure in tunnels
Osgoui, Reza. R. (2006-06-21)
This paper presents a newly empirical approach to estimate support pressure in rock tunnels. The new approach takes the rock mass quality (Geological Strength Index: GSI), the disturbance degree, the post-failure behavior, the size of tunnel, the state of in-situ stresses, and the squeezing-prone condition into consideration. A parametric study was, too, carried out using numerical analysis to investigate the influence of anisotropy in field stresses and the effect of the various shapes and sizes of tunnels...
Seismic response and vulnerability assessment of Tunnels: a case study on Bolu Tunnels
Üçer, Serkan; Bakır, Bahadır Sadık; Department of Civil Engineering (2012)
The aim of the study is to develop new analytical fragility curves for the vulnerability assessment of tunnels based on actual damage data of tunnels obtained from past earthquakes. For this purpose, additional important damage data belonging to Bolu Tunnels, Turkey was utilized as a case study. Bolu Tunnels constitute a very interesting case from the earthquake hazard point of view, since two major earthquakes, 17 August 1999 Marmara and 12 November 1999 Düzce, occurred during the construction of the tunne...
Verification of empirically determined support systems of the Kılıçlar highway tunnel by numerical modelling
Çelik, Gözde; Topal, Tamer; Department of Geological Engineering (2011)
The aim of this study is to determine the geological and geotechnical characteristics of Kılıçlar Tunnel on Ankara-Kırıkkale Highway, to suggest the appropriate support and excavation systems and verify these suggested support systems via numerical modeling. The length of Kılıçlar Tunnel is 1110 m. The width of tunnel is 16 m, the height is 10 m and the maximum overburden height is 90 m. Since Ankara-Kırıkkale Highway consists of 2x3 lanes, the tunnel is designed as a twin tube tunnel. Kılıçlar Tunnel is pl...
