In this study a recent dam type, concrete face rockfill dam (CFRD), its design and behaviour is overviewed. The design features of Gökçeler Dam are introduced as a case study. Selection of concrete face rockfill type for Gökçeler Dam Project is discussed together with the other two alternatives, namely earth core rockfill (ECRD) and roller compacted concrete (RCC) dam. Gökçeler Dam type selection as concrete face rockfill dam is also verified by an economic analysis conducted calculating internal rate of return for all alternative types. In cost analysis a currency independent defined unit cost (DUC) is specified to verify the time independent validity of the economic analysis.

An analysis of deformation behaviorof Muratlı asphalt faced rockfill dam Ünsever, Yeşim Sema; Özkan, M. Yener; Department of Civil Engineering (2007) In this study, settlement and seepage behavior of Muratlı Dam, which is the first asphalt faced rockfill dam in Turkey, is investigated for the “end of construction” and “reservoir impoundment” loading conditions. Two dimensional plane strain finite element analyses are carried out in order to determine the total stresses, displacements and pore water pressures. Hardening soil model is used in order to represent the non-linear, inelastic and stress dependent behavior of rockfill material. Material model par...
Ön yüzü beton kaplı kaya dolgu barajların sismik performanslarının irdelenerek tasarıma uygun kılavuz yöntemlerin geliştirilmesi Arıcı, Yalın; Binici, Barış(2012) Concrete faced rockfıll dam (CFRD) is an increasingly favoured dam type in the world along with the RCC dams. The design procedure for CFRDs, based on past experience, was significantly questioned after the poor performance of a number of recently built systems. The performance of CFRDs under earthquake were deemed exquisite; however, this preposition is hard to verify due to the scarcity of CFRDs subjected to very strong ground motions. The significance of this study stems from the determination of the wor...
Settlement behaviour of concrete faced rockfill dams : a case study Özkuzukıran, Rıza Savaş; Özkan, M. Yener; Department of Civil Engineering (2005) In this study settlement behaviour of Kürtün dam, which is the first concrete faced rockfill dam in Turkey, is investigated. Two dimensional plane strain finite element analyses are carried out in order to determine the total stresses and displacements during construction and reservoir filling conditions. Hardening soil model is used in order to represent the non-linear, inelastic and stress dependent behaviour of rockfill material. Material model parameters are selected mainly referring to the previous stu...
An evaluation study on instrumentation system of Cindere dam Sezgin , Özgün İlke; Yanmaz, Ali Melih; Department of Civil Engineering (2008) In this study, the first hardfill dam in Turkey, Cindere Dam, is evaluated regarding current and alternative measurement systems in detail. Cindere Dam is a notable project, especially with its height as an example of hardfill dam, not only in Turkey but also in the world. First, the current instrumentation system of Cindere Dam is evaluated as a whole with reference to the parameters measured, instruments and data acquisition system. Second, an alternative instrumentation system is developed by using addit...
An integrated seismic hazard framework for liquefaction triggering assessment of earthfill dams' foundation soils Ünsal Oral, Sevinç; Çetin, Kemal Önder; Department of Civil Engineering (2009) Within the confines of this study, seismic soil liquefaction triggering potential of a dam foundation is assessed within an integrated probabilistic seismic hazard assessment framework. More specifically, the scheme presented hereby directly integrates effective stress-based seismic soil liquefaction triggering assessment with seismic hazard analysis framework, supported by an illustrative case. The proposed methodology successively, i) processes the discrete stages of probabilistic seismic hazard workflow ...
