A thorough research on excavability of draglines at TKI Tungbilek Mine has been started consisting of determination of the excavability of the marl formation under diflerent excavation conditions such as blasted, unbiasted and spoil heap material. A particular monitoring system has been developed for this purpose. The digging, fuli and empty operations both time wise and energy wise can be monitored in full cycle. The monitoring system has 16 channel recording capacity with a 60kllz sampling rate The response of machine excavability against digging conditions are charactensed by armature voltage and armature current values of drag, horst and swing motors. Energy consumptron of each motor has been calculated. Finally, specific and trme normalized digging energies are presented in each cycle for different digging conditrons In this paper, emphasise is given both on the monitoring system and the results obtained.

Performance Analysis of Existing Vs30 Prediction Models for Turkey and New Approaches to Improve Okay, Hakan Bora; Özacar, Atilla Arda (2022-04-11) Various parameters are used for geotechnical characterization and considering seismic site conditions. Among them, the most widely used one is the average shear wave velocity (Vs30) of the first 30 meters of the Earth's surface. Within the scope of the study, Vs30 measurements of accelerometer stations which are operated by the Disaster and Emergency Management Presidency (AFAD) throughout Turkey, were mapped, and the slope and elevation values of these points were calculated using high resolution di...
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...
Optimal dewatering of an excavation site Demirbas, Korkut; Altan Sakarya, Ayşe Burcu; Önder, Halil (2012-06-01) Optimal dewatering of an excavation area in an unconfined aquifer is studied using a combined optimisation-simulation approach. In combining a groundwater model with an optimisation model, a response matrix approach, generated on the basis of linear superposition, is used. ModMan, which calls Modflow repeatedly to generate a response matrix, is utilised to transform the groundwater management problem into a linear integer programming problem. A hypothetical dewatering area is considered to examine the effec...
Reliability-based evaluation of scouring around dual bridge piers Yilmaz, Meric; Çalamak, Melih; Yanmaz, Ali Melih (Croatian Association of Civil Engineers, 2019-01-01) The causes of uncertainty involved in temporal variation of the depth of cavern formation due to clear water scouring at dual piers with tandem arrangement are identified in this study. In an example, the probability of failure induced by scouring around dual piers is estimated for various pier spacing using probabilistic analysis. The effects of changes in the coefficient of variation of probabilistic scouring variables and probability distributions on the probability of the loss of stability, are also inv...
Effective stress based constitutive modelling and assessment of seismic pile-soil interaction in liquefiable soils Ünsal Oral, Sevinç; Çetin, Kemal Önder; Department of Civil Engineering (2014) The assessment of liquefaction-induced deformations of foundation soils located in seismically active regions has been a major concern for geotechnical earthquake engineers. Inspite of the existing efforts, the prediction of these deformations has remained a "soft" area of practice. Inspired by this gap, a new fully coupled, two-dimensional, effective stress-based, nonlinear and simplified constitutive model, referred to as METUSAND, is developed. As a part of the model development efforts, a “C++” subrouti...
