An Investigation of geotechnical characteristics and stability of a tailings dam

Sayıt, Emir
The objective of this study is to investigate the stability problems in tailing (i.e. mine waste) dams. A tailing dam is an embankment dam (made of natural borrow or tailing material) constructed to retain slurry-like mining wastes that are produced as a result of operation of mines. In the last 30 years, the stability of tailing dams has drawn much attention as a significant number of tailing dam failures have been recorded worldwide. These instability problems caused significant loss of life and damage to property in addition to environmental hazards. In this study causes of failure of tailing dams and their stability problems are investigated with respect to their geometric and material characteristics. Seepage and stability of tailing dams are studied through limit equilibrium method and finite element method. The effects of uncertainties in material properties on the stability of tailings dams is investigated. Within this context, Kastamonu-Kure copper tailings dam is used as a case study and material properties are determined by laboratory tests.


Probabilistic modeling of plane failure in rock slopes
DUZGUN, HSB; Yücemen, Mehmet Semih; Karpuz, Celal (2003-07-09)
The basic aim of this study is to formulate a probabilistic method by which sources of uncertainties can be taken into account and systematically analyzed in dealing with the rock slope stability problem. For this purpose, the advanced first-order second-moment (AFOSM) method and the Monte Carlo simulation (MCS) procedure are used to model the plane failure problem in rock slopes. The modeling of plane failure by the AFOSM and the MCS methods requires the understanding of the basic mechanism of plane failur...
An experimental investigation on the chemical stability of selected formation and determination of the proper type of water-base drilling fluids. Part 1. Descriptive tests
Erkekol, Selcuk; Gucuyener, I. Hakki; Kök, Mustafa Verşan (Informa UK Limited, 2006-07-01)
The objective of this study was to identify the descriptive tests for drilling stable holes through the problems of the selected formations. This study was performed on the shale samples taken from 10 wells in which hole instability was encountered to various extents during drilling the Germav formation. A total of 13 formation samples, characterizing the problematic intervals of the 10 wells under consideration, were evaluated. Descriptive tests were used to compare the samples and to determine the samples...
A comprehensive evaluation of possible eutrophication control methods for Keban dam reservoir with special emphasis on pre-dam construction
Karul, C; Soyupak, S; Tuncer, A; Mukhallalati, L; Cilesiz, AF (1997-05-01)
This study evaluates the available eutrophication control techniques that could be applied in Keban Dam Reservoir. A limited reduction of phosphorous was shown to be achieved by pre-dam construction on the major nutrient source, Murat River. Biomanipulation was evaluated as an ineffective method. A performed analysis has shown that only a drainage basin management program may decrease the phosphorous loading to the extent desired.
An Investigation of the Ground Motion Scaling Procedures for the Nonlinear Seismic Analyses of Concrete Gravity Dams
Soysal, BERAT FEYZA; Ay, Bekir Özer; Arıcı, Yalın (2019-07-03)
Seismic assessment of gravity dams is generally carried out using time history analyses. Scaling of the motions is commonly used; however, in contrast to buildings, the performance of scaling procedures at predicting the mean and reducing the dispersion in engineering demand parameters (EDPs) is not known. The main goal of this study is to assess the performance of different scaling procedures in predicting seismic demands on dams. The performance regarding the prediction of the damage and the required numb...
Effects of berm characteristics on earth-fill dam stability
Kılıç, Yasin; Yanmaz, Ali Melih; Çalamak, Melih; Department of Civil Engineering (2017)
One of the causes of failure in earth-fill dams is the slide of the slope. For this reason, slope stability is a crucial issue for dam safety. There are some precautions to increase the safety of earth-fill dams, and constructing berms on upstream or downstream sides is one of these ways. In this study, effects of berm properties on dam stability are investigated with a case study. The effects of different berm heights, numbers and widths on the stability of Hancağız Dam, Turkey, are analyzed by using three...
