This paper investigates the shear strength of municipal solid waste (MSW) using the back analysis of failed waste slopes as well as field and laboratory test results. Shear strength of MSW is a function of many factors such as waste type, composition, compaction, daily cover, moisture conditions, age, decomposition, overburden pressure, etc. These factors together with non-standardized sampling methods, insufficient sample size to be representative of in situ conditions, and limited shear displacement or axial strain imposed during the laboratory shear testing have created considerable scatter in reported results. Based on the data presented herein, large shear displacements are required to mobilize the peak shear strength of MSW which can lead to displacement incompatibility between MSW and the underlying material(s) such as geosynthetic interfaces and foundation soils. The data presented herein are used to develop displacement compatible shear strength parameters for MSW. Recommendations are presented for modeling the displacement and stress dependent strength envelope in stability analyses.

Evaluation of a compacted bentonite/sand seal for underground waste repository isolation
Akgün, Haluk; AKTÜRK, ÖZGÜR (Springer Science and Business Media LLC, 2006-06-01)
This study investigates the performance of an optimum compacted bentonite/sand mixture seal for the isolation of underground waste repositories. Engineering geological tests such as compaction, flow, swelling, mechanical and shear strength tests have been conducted to select an optimum mixture and to recommend a stable bentonite/sand seal length-to-radius ratio (L/a) as far as the factor of safety (F) is concerned. The results of the compaction permeameter tests led to a recommendation to select an optimum ...
Finite element simulation of seawater intrusion into a quarry-site coastal aquifer, Kocaeli-Darica, Turkey
Karahanoğlu, Nurkan (Springer Science and Business Media LLC, 2003-07-01)
A numerical simulation has been carried out to investigate the effects of below-sea-level (b.s.l.) excavation on the raw material quality of a cement quarry in Turkey. The model simulates variations in the hydrodynamic and hydrogeochemical mechanisms in the coastal aquifer upon BSL excavation. In this context, behavior of the seawater intrusion zone, changes in water levels, and salt concentrations have been simulated. In the development of the model, previous geological and hydrogeological reports of the q...
Composite landfill liner design with Ankara clay, Turkey
Met, İlker; Akgün, Haluk (Springer Science and Business Media LLC, 2005-04-01)
This study presents an overview of the geotechnical properties of the clayey soils, referred to as "Ankara clay", at two sites of the Ankara region in an attempt to design a landfill profile composed of a high density polyethylene (HDPE) geomembrane/clay composite liner through the Hydrologic Evaluation of Landfill Performance (HELP) model and the Water Balance Method. The geotechnical properties of the landfill layers along with the water balance factors (i.e., evapotranspiration, precipitation, temperatur...
Lined waste containment systems: A method for design and performance evaluation
Akgün, Haluk (Springer Science and Business Media LLC, 1997-04-01)
The objective in designing lining systems for the containment of the leachate generated within a landfill is the prevention of contamination of groundwater and surface waters. The technology involving the design of these systems has progressed to a point that the integrity of the containment can be relied on over the long term. Double-lined systems provide the additional benefit of being able to quantify the performance of the lining system through the detection of leakage through the upper liner. The diffi...
Assessment of soil acidification due to a natural gas-fired power plant by using two different approaches
Soyupak, S; Yurteri, C; Mukhallalati, L; Kilic, B; Kayin, S; Onder, K (Informa UK Limited, 1996-01-01)
Potential soil acidification impacts of a proposed natural gas-fired combined cycle power plant were assessed using an integrated approach coupling an atmospheric deposition model with soil acidification quantification. The deposition model was used to estimate the rates of nitrogen oxide (NOx) deposition on the air-soil boundary. The expected changes in the soil column were then predicted by utilizing mechanistic and experimental methods, and the number of years required to reach critical pH values were pr...
