New procedures for the design of precast segmental lining tunnels have been developed in recent years. The use of glass fiber reinforced polymer (GFRP) bars instead of conventional steel bars is increasing in precast segments. Besides, macro-synthetic fibers are also used as a replacement for traditional steel bars. It is possible to find design guidelines for the design of precast segments reinforced with GFRP or fiber reinforced concrete (FRC) precast segments with or without conventional reinforcement. However, to the best of the authors' knowledge, there is no design code or guideline for a design methodology for the combination of the two, macro-synthetic FRC tunnel segments reinforced with GFRP. A design procedure is proposed for macro-synthetic FRC precast linings reinforced with GFRP. The purpose of this study is to develop a method for the design according to the temporary load cases as well as permanent loadings for both ultimate limit state (ULS) and serviceability limit states (SLS).

A Method for the design of FRC tunnel linings reinforced with FRP bars
Demir, Mutlu; Akyüz, Uğurhan; Department of Civil Engineering (2019)
There are some difficulties in the construction of precast conventional reinforced concrete tunnel segments. Due to corrosion problem of ordinary reinforcement, the task becomes more complicated. Moreover, the workmanship for the construction of segments is also very time consuming. There are some research for the design of tunnel segments with fiber reinforced polymer (FRP) bars. Besides, guidelines for the design of fiber reinforced concrete (FRC) tunnel linings are also available. This thesis provides a ...
AN EXPERIMENTAL STUDY ON THE CHARACTERISTICS OFn HEPTANE ETHANOL MIXTURE POOL FIRE IN A REDUCED SCALE TUNNEL
Yamalı, Uluç; Shafee, Sina; Yozgatlıgil, Ahmet (2015-09-11)
Fire accidents in recent decades have drawn attention to safety issues associated with the design, construction and maintenance of tunnels. A reduced scale tunnel model constructed based on Froude scaling technique is used in the current work. Mixtures of n-heptane and ethanol are burned with ethanol volumetric fraction up to 30 percent and the longitudinal ventilation velocity varying from 0.5 to 2.5 m/s. The burning rates of the pool fires are measured using a precision load cell. The heat release rates o...
An empirical method for design of grouted bolts in rock tunnels based on the Geological Strength Index (GSI)
Osgoui, Reza R.; Unal, Erdal (Elsevier BV, 2009-08-14)
The procedure presented in this paper has been developed for the design of grouted rock bolts in rock tunnels during preliminary design stage. The proposed approach provides a step-by-step procedure to set up a series of practical guidelines for optimum pattern of rock bolting in a variety of rock mass qualities. For this purpose, a new formula for the estimation of the rock load (support pressure) is recommended. Due to its wide-spread acceptance in the field of rock engineering, the Geological Strength In...
An Experimental study of particle size and concentration effects of calcium carbonate on rheological and filtration properties of drill-in fluids
Odabaşı, Aydın; Kök, Mustafa Verşan; Gücüyener, İ. Hakkı; Department of Petroleum and Natural Gas Engineering (2015)
Specially designed non-damaging Drill-In Fluids (DIF) are being effectively applied for drilling depleted zones worldwide. Shape, particle size distribution and concentration of materials like calcium carbonate (CaCO3) are key parameters determining the effectiveness of DIF. In this study, 3 different sized and 5 different concentrations CaCO3 are used to examine the effects of these factors on rheology and fluid loss of DIF. Sized calcium carbonates are used as major particles in different concentrations a...
A Comparative Experiment Study on Precast Tunnel Segments
Akyüz, Uğurhan; Talu, Erhan; Mert, Selcuk (2020-09-11)
Increasing popularity of using fibres in concrete has brought questions about their usability in segmental tunnel linings as an alternative to the conventional lining. Prior studies have already revealed that the replacement of conventional steel reinforcement is possible with steel fibres. However, the usability of macro-synthetic fibres (MSFs) as reinforcements in precast tunnel segments is still unclear and one of the controversial questions to be answered. This study aims to evaluate the structural a...
