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 working principles of these dams and the factors affecting CFRD performance based on detailed analytical studies, in lieu of the empirical experience. All constituents of the system were modeled using detailed material models calibrated to laboratory experiments and the cracking of the face plate was investigated over the whole operation period including the first reservoir loading, seismic loading and creep of the fill. The results of the study show that the cracking on the plate is the primary reason for the seepage from these dams, not the openings in the joints commonly suggested in previous studies. The effect of the design parameters on the cracking pattern of the face plate was investigated and the rigidity of the rockfill and reinforcement ratio were determined to be the two most important factors determining seepage. The results of the detailed 3D analyses showed that crushing effects should seriously be considered for these systems under strong earthquakes. Soil-structure interaction effects were investigated leading to suggestions on simulations and modeling; the use of simple modeling techniques for simulation of sand-gravel fill dams on alluvium layers were shown to be misleading. Along with the contribution to the scientific literature with the publications within the project duration, the work conducted has led to a range of suggestions which can be used for modelling and design in the industry. It is believed that the procedure developed in the last part of this report is going to contribute to dam engineering in improving on empirical design procedures.

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...
Evaluation of concrete face rockfill alternative for dam type selection: a case study on Gökçeler Dam
Korkmaz, Seda; Yanmaz, Ali Melih; Department of Civil Engineering (2009)
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 re...
Finite element analysis of deformation behavior of concrete faced Konya Afşar Hadimi dam and comparison of results with measurements
Kardeş, Doğuşcan; Çokça, Erdal; Department of Civil Engineering (2019)
To eliminate the problem of scarcity of appropriate fill material in the vicinity of construction site, concrete faced dam is a commonly preferred alternative for embankment dams. Functioning as an impervious membrane, the concrete face makes it possible to use dumped rockfill, compacted rockfill or sand-gravel fill as the dam body material. In this study, deformation behavior of Konya Afşar Hadimi Dam, which is a concrete faced rockfill dam, was investigated by finite element analyses using Plaxis and Mida...
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...
Deformation analysis of concrete faced Aydın Karacasu dam and comparison of theoretical results with measurements
Tütüncübaşı Tosun, Tuğçe; Çokça, Erdal; Özkan, M. Yener; Department of Civil Engineering (2015)
The improvement in design technologies has enhanced the use of different fill materials in construction of the embankment dams. Rockfill is one of the most preferred fill materials for embankment dam. Also, use of different fill material such as sand-gravel has been preferred in recent years. Previous studies on concrete faced sand-gravel fill dam, results of the laboratory experiments and in-situ testing analysis display that using sand-gravel as a fill material is not only cost-effective but also safe and...
