This paper investigates the shear strength of municipal solid waste (MSW) using back analyses of failed waste slopes. 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 shear tests affect the test results and have created considerable scatter in reported test results. This scatter led the authors to pursue the back-analysis of failed waste slopes as a better means for estimating the shear strength of MSW. The back-analysis of failed waste slopes in the Gnojna Grora landfill in Poland, Istanbul Landfill in Turkey, Hiriya Landfill in Israel, and Payatas Landfill in Philippines are presented in this paper. Each of the landfill slope failures is reviewed and the results of the back-analyses presented. Finally, comparison of the recommended shear strength envelope of MSW and those by various researchers for the design of landfill slopes is presented.

Shear strength of municipal solid waste for stability analyses
Stark, Timothy D.; Huvaj Sarıhan, Nejan; Li, Guocheng (Springer Science and Business Media LLC, 2009-06-01)
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 ax...
Effective flexural rigidities for ordinary reinforced concrete columns and beams
AVŞAR, ÖZGÜR; BAYHAN, BEYHAN; Yakut, Ahmet (Wiley, 2014-04-25)
Current effective flexural rigidities proposed for use in design and analyses of reinforced concrete structures have been examined. The level of accuracy in the estimation of section rigidity plays a very important role in determining realistic values for the structural stiffness and hence the seismic forces imposed. The most significant parameters influencing the effective rigidity, which reflects the effect of cracking as well as the theoretical yielding of reinforced concrete sections, have been determin...
Alternative solutions for long missing streamflow data for sustainable water resources management
Mesta, Buket; Akgün, Ömer Burak; Kentel Erdoğan, Elçin (Informa UK Limited, 2020-08-01)
Sustainable water resources management requires long time series of streamflow data. In this study, a Takagi-Sugeno fuzzy rule-based (FRB) model is developed to reconstruct long periods of missing daily streamflow data which is a common problem in developing countries. The FRB model uses observations of neighbouring stream gauges, and thus is advantageous regarding data and time requirement compared to physical models. With the proper set of inputs, the FRB model provides better estimates than the hydrologi...
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...
Hybrid fiber reinforced self-compacting concrete with a high-volume coarse fly ash
Sahmaran, Mustafa; Yaman, İsmail Özgür (Elsevier BV, 2007-01-01)
This paper presents a study on the fresh and mechanical properties of a fiber reinforced self-compacting concrete incorporating high-volume fly ash that does not meet the fineness requirements of ASTM C 618. A polycarboxylic-based superplasticizer was used in combination with a viscosity modifying admixture. In mixtures containing fly ash, 50% of cement by weight was replaced with fly ash. Two different types of steel fibers were used in combination, keeping the total fiber content constant at 60 kg/m(3). S...
