Improvement of the penetration rates with respect to some operational and formation properties in exploration drilling in Turkiye


Utilization of Ankara Clay for Sanitary Landfill Bottom Liners Turkey
Akgün, Haluk (2005-01-01)
This study aims at determining the geotechnical properties and the compaction permeability characteristics of a clayey soil sample obtained from the Göbaşi site of the Ankara region in an attempt to assess its suitability as a compacted clay liner. The soil sample was permeability tested at about 3% wet of its optimum moisture content using the falling head compaction permeameter apparatus. The expected leakage rates through clay-only and composite geomem-brane-clay liners constructed with compacted Ankara ...
Evaluation of displacement coefficient method for seismically retrofitted buildings with various ductility capacities
Dicleli, Murat (Wiley, 2014-07-25)
This research study is aimed at evaluating the accuracy of the displacement coefficient method (DCM) of FEMA 440 and associated nonlinear static procedure (NLSP) for actual buildings with soft story mechanism and various ductility capacities. The DCM and associated NLSP are evaluated using two existing seismically vulnerable buildings with soft story mechanism. The buildings are first retrofitted using a ductile steel-brace-link system to represent those with good ductility capacity and then retrofitted wit...
Application of Rock Mass Classification Systems for Future Support Design of the Dim Tunnel Near Alanya
Coşar, Songül; Ünal, Erdal; Department of Mining Engineering (2004)
In this thesis, the results of a number of rock mass classification systems applied to Dim-higway tunnel study area are presented. The tunnel ground was classified according to Rock Mas Rating (RMR), Modified Rock mass Rating (M-RMR), Rock mass quality (Q), Geological Strength Index (GSI) and New Austrian Tunneling Method (NATM). Dim Tunnel has a horse-shoe shape, with a diameter of 10 meters and maximum overburden thickness of 70 meters. During studies, the geological and geotechnical characteristics of th...
Modification of magnetic properties of siderite by thermal treatment
Alkaç, Dilek; Atalay, M Ümit; Department of Mining Engineering (2007)
Obtaining high magnetic susceptibility phases from HekimhanDeveci siderite orevia preliminary thermal treatment has been the basic target of the thesis study.Thermal decomposition characteristics of samples, determined bythermogravimetric analysis (TGA), differential thermal analysis (DTA), and differential scanning calorimetry (DSC), were referenced in advancement of thestudy. Heat treatment experiments, particularly roasting, were carried out byconventional heating and microwave heating. Results showed th...
Estimation of lining thickness around circular shafts
Ozturk, H; Unal, E (2001-06-22)
In this paper, the broken zone developing, around a circular mine shafts and lining pressure is estimated by integrating the results of numerical analysis and the "rock-load height" equation derived from empirical analysis. During numerical modelling studies, the computer program FLAC(2D) was utilized. In order to estimate equivalent Mohr failure Envelope from the generalised Hoek Brown failure criterion, a new FISH function was written within FLAC(2D). Parametric studies were carried out by considering mRM...
