This paper describes the results of engineering geological and rock mechanics studies carried out at the Güledar irrigation dam project. Project is designed to regulate the drainage and to irrigate the agricultural areas. The dam site is located within Güledar Sirkeli formations composed of sandstone, limestone and diabase. Studies maintained both at field and laboratory. Field studies included geological mapping, core drilling, sampling for laboratory testing, pressurized water tests, and intensive discontinuity surveying. Some physical and mechanical properties were determined at laboratory. The rock mass qualities of rock units were determined, and described as poor to fair quality. The corresponding Hoek and Brown failure envelopes have been drawn and failure equations have been suggested for stability analysis of dam foundation, slope stability and diversion tunnels for each rock unit. L'article résume les études géotechniques et de mécanique des roches réalisées sur le site du barrage de Güledar, destiné à l'irrigation et à la régulation du drainage de terres agricoles. Il sé situe dans des formations constituées de grès, calcaire et diabase. Les études de terrain ont compris: la cartographie géologique, des sondages carottes, l'échantillonnage pour essais de laboratoire des essais d'eau sous pression et un relevé détaillé des discontinuités. Quelques propriétés physiques et mécaniques ont été mesurées en laboratoire. Les masses rocheuses ont été classées en fonction de leur «qualité». Les analyses de stabilité de la fondation du barrage, des pentes et des tunnels de dérivation ont été effectuées pour chaque unité rocheuse par la méthode de Hoek et Brown.

A Methodology for Optimal Layout Design of Pressure Cells for Concrete Faced Rockfill Dams Arı, Onur; Yanmaz, Ali Melih (Springer Science and Business Media LLC, 2018-08-01) In this study, a methodology for optimal layout design of pressure cells for concrete faced rockfill dams is developed. A representative dimensionless stress distribution model was formed for obtaining the magnitudes and location of different stress zones as a function of dam height. This information enabled development of a procedure for proper location and the number of pressure cells throughout the dam body. A vertical placement algorithm based on error minimization was first developed, which is followed...
A Semi-empirical method for estimation of maximum seismic shear strain in imperforated ground excited by vertically propagating shear waves Dehghanian, Kaveh; Yılmaz, Mustafa Tolga; Department of Engineering Sciences (2016) Seismic design of underground structures requires calculation of the deformation in surrounding geological formations. The seismic hazard on a site is usually expressed as a function of amplitude parameters of free-field motion. Therefore, simplified relations between depth and parameters of ground motion are necessary for preliminary designs. The objective of this study is to employ random vibration theory to develop a simple relationship between maximum shear strain (γmax), depth, and ground-motion intens...
A proxy model for determining reservoir pressure and temperature for geothermal wells Aydin, Hakki; Akın, Serhat; Senturk, Erdinc (Elsevier BV, 2020-11-01) Estimating reservoir pressure and temperature is one of the challenges of geothermal reservoir engineering. A new proxy model has been developed to estimate reservoir pressure and temperature using wellhead pressure, temperature and non-condensable gas (NCG) amount. An exhaustive set of wellhead data covering a range of possible wellhead pressure, temperature and NCG data is used in a calibrated wellbore simulator, which is then used to create a knowledgebase to train an artificial neural network (ANN) mode...
A Comparative assessment of seismic soil liquefaction triggering relationships Ilgaç, Makbule; Çetin, Kemal Önder; Department of Civil Engineering (2015) Starting with 1964 Niigata and Alaska Earthquakes, seismic soil liquefaction behavior has become a major research stream in geotechnical earthquake engineering. Since then, a number of investigators (e.g.: Seed et. al. (1984), Liao et. al. (1988, 1998), Toprak et. al. (1999), Cetin et. al. (2004) and Idriss and Boulanger (2004, 2008, 2012)) introduced deterministic and probabilistic liquefaction triggering assessment methodologies. The scope of this study is to develop an SPT-based seismic soil liquefaction...
An Investigation of landslide at KM: 12+200 of Artvin - Savsat junction - Meydancık provincial road Topsakal, Ebru; Topal, Tamer; Department of Geological Engineering (2012) The purpose of this study is to determine the most suitable remediation techniques via engineering geological assessment of the landslide that occurred during the construction of Artvin-Şavşat Junction - Meydancık Provincial Road at Km: 12+200 in an active landslide area. For this purpose, the geotechnical parameters of the mobilized geological material which is colluvium along the sliding surface were determined by back analyses of the landslide at three geological sections. The landslide were then modeled...
