This thesis identifies the geotechnical parameters of the Antalya karstic foundation rocks (travertine/tufa), which are highly variable in nature, by means of geological observations, geotechnical site investigations, and field and laboratory geomechanics tests to examine karstic (mainly tufa) rock mass behavior. Several geotechnical parameters such as porosity, seismic wave velocity, uniaxial compressive strength, Young’s modulus, tensile strength, etc. that are thought to have significant influence on rock mass behavior have been tested and statistically analyzed. Principal component analysis and multiple linear and non-linear regression analyses have been carried out in order to reveal correlations between the geotechnical parameters tested. Porosity has been statistically determined to be one of the major parameters governing the strength of the Antalya tufa rock mass. Intact rock failure criteria, among which Bieniawski’s criterion has been proven to be more appropriate for each tufa type (phytoherm framestone, phytoherm boundstone, microcrystalline tufa, phytoclast tufa and intraclast tufa) along with the Antalya tufa rock mass have been determined from the experiments. GSI rock mass classification of the Antalya tufa rock mass, whose GSI value was recommended between 20±5 and 75±5, has been attempted to be used in engineering design. Furthermore, the depth and dimension of the karstic cavities and fractures have been investigated by the geophysical tests, surface geological survey and subsurface investigations (borings and observation pits).

Engineering geological and geotechnical site characterization and determination of the seismic hazards of Upper Pliocene and Quaternary deposits situated towars the west of Ankara
Koçkar, Mustafa Kerem; Akgün, Haluk; Department of Geological Engineering (2006)
The purpose of this study is to assess the engineering geological and geotechnical characteristics and to perform seismic hazard studies of the Upper Pliocene and Quaternary deposits located towards the west of Ankara. Based on a general engineering geological and seismic characterization of the site, site classification systems are assigned for seismic hazard assessment studies. The objective of the research is to determine the regional and local seismic soil conditions, predominant periods and ground ampl...
Engineering Geological Characterization of the Antalya Karstic Rocks
EVRIM, Sopaci; Akgün, Haluk (2014-09-19)
This paper presents the identification of the geotechnical parameters of the Antalya karstic foundation rocks (travertine/tufa), whose mechanical behavior is highly variable due to its composition. Antalya tufa rock has numerous types/members of tufa, each has different structures. It has no well-developed joint system and is variably porous. In order to reveal the controlling geotechnical parameters for the mechanical behavior of the Antalya tufa rock and to develop a comprehensive geotechnical database, n...
Petrography and mineral chemistry of the basaltic rocks and dykes from the Burunköy (Çorum) region, Turkey
Atak Küçük, Aynur; Köksal, Fatma; Department of Geological Engineering (2014)
Petrography and mineral chemistry of the basaltic rocks and dykes, which are outcropping in the Burunköy (Çorum) region, are discussed in the scope of this thesis. The studied rocks belong to the ophiolitic melange of İzmir-Ankara-Erzincan Suture Zone that were derived from the closure of northern branch of Neotethys. In the study area, the metamorphic rocks of Sakarya Composite Terrane tectonically overlies the ophiolitic melange units, and Upper Neocene sediments cover both units unconformably. The rocks ...
Sedimentary basin deformation: an incremental stress approach
Tuncay, Kağan; Ortoleva, P. (Elsevier BV, 2000-8)
A key component of sedimentary basin evolution is the spatial distribution and temporal variation of stress and deformation. The many deformation processes (poroelasticity, fracturing, irreversible nonlinear viscosity, and pressure solution) are inextricably bound in a tightly coupled network which, in turn, is coupled to a myriad of basin diagenetic, thermal and hydrologic processes. In the approach presented here, the various deformation processes are integrated through an incremental stress approach. Tog...
Thermal Anomaly and Alteration Mineral Mapping in İzmir Dikili Region by using ASTER and Investigation of the Geothermal Potential of the Region
Cambazoğlu, Selim; Yal, Gözde Pınar; Eker, Arif Mert; Koçkar, Mustafa Kerem; Osman, Şen; Akgün, Haluk (null; 2014-03-14)
This study encompasses the detection, mapping and validation of hydrothermal alteration types and minerals, surface temperature anomaly mapping utilizing remote sensing methods in order to assess the geothermal potential of the Dikili region. The study area covers Bergama, Dikili, Çandarlı and Altınova districts located at the northern part of İzmir Province where fumaroles and numerous thermal water outflows with temperatures between 63°C and 89°C are present. The study area is located at the northern part...
