Deformation behavior of a clay cored rockfill dam in Turkey

Oral, Yaşar Zahit
In this study, Bahçelik Dam, which is located in Kayseri Province, is investigated by means of horizontal movement due to reservoir loading and seepage inside the core and body. Two dimensional plain strain finite element analyses are carried out in order to find total stresses, displacements and pore water pressures. Mohr-coulomb soil model is used to represent elastic behavior of rock-fill material. Since there is no information about material used in dam body, material parameters are determined by sensitivity analyses being in the range of data acquired from literature survey. Calculated displacement and pore water pressures are compared to the data taken from field survey on actual dam body. As a conclusion remark, it is beleived that the horizontal displacement behaviour of two systems, such as real dam and computer modelling, would not match excatly since the materials used in real dam body would behave as plastic whereas that used in computer modelling assumed to be elastic.


Seismic Performance Evaluation of Concrete Gravity Dams by Using Pseudo Dynamic Testing and Simulations
Aldemir, Alper; Binici, Barış (null; 2017-11-24)
Dams are one of the mostimportantinfrastructure components servingfor water storage and energyproduction.Experimental studies on the seismic response of concrete gravity dams are scarce due to the complications regarding thelargescaleof dams and their interaction with the reservoir. This study presents the results of recent novel pseudo-dynamic dam tests (PSD) along with the nonlinear finite element simulations of the specimens. The test specimens were 1/75 scaled version of the highest ...
Numerical modeling of seawater groundwater relationships in the Selçuk sub basın, İzmir Turkey
Hassan, Abubakr; Çamur, Mehmet Zeki; Department of Geological Engineering (2004)
Seawater-fresh groundwater natural equilibrium conditions in the aquifers of the Selçuk sub-basin may be disturbed by the discharge occurred during the past 30 years in order to supply water for irrigation and domestic purpose usage. Two dimensional density dependent cross sectional saturated flow and solute transport simulations were carried out to determine whether seawater intrusion has occurred in the Selçuk sub-basin due to the imposed discharge or the determined salt-water in the western section of th...
Geotechnical rock-mass evaluation of the Anamur dam site, Turkey
Ozsan, A; Karpuz, Celal (Elsevier BV, 1996-03-01)
This paper describes a feasibility-level geotechnical evaluation carried out at Anamur dam site, in terms of stability analysis of dam foundation, excavation slopes and a diversion tunnel. The proposed Anamur dam will be built across the Anamur river on the Alanya metamorphic series which consists of phyllite, schist and slate units at the site. Geotechnical investigations included drilling for core, pumping tests, sampling for laboratory testing, and a detailed discontinuity survey.
Mafic microgranular enclaves and interaction between felsic and mafic magmas in the agacoren intrusive suite: Evidence from petrographic features and mineral chemistry
Kadioglu, Yusuf Kagan; Güleç, Nilgün Türkan (Informa UK Limited, 1996-01-01)
The Agacoren Intrusive Suite is exposed as a large intrusive body over ∼500 km2 east of Lake Tuz in central Anatolia and consists of the Cokumkaya gabbro, the Agacoren granitoid, and young dikes. The Agacoren granitoid is the predominant lithology of the Agacoren Intrusive Suite, and is differentiated into several subunits ranging in composition from monzonite, through granite, to alkali feldspar granite. The Cokumkaya gabbro occurs as stocks enclosed in the Agacoren granitoid; individual bodies range in si...
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...
