Summary:

      In this study, solid waste management strategy and its faults were investigated in Trabzon City, landfill suitability map were prepared by using AHP and spatial analysis techniques. It is concluded that, Düzyurt area was suggested as the most suitable landfill site for Trabzon and geotechnical investigations were performed in this site.

The geological units are the Late Cretaceous aged Çağlayan Formation, Late Cretaceous-Paleocene aged Tonya Formation, Eocene-Neojene aged Kabaköy Formation and Quternary alluvium in the area.

      Subsurface and surface studies were conducted for description of vertical and horizontal homogeneity of geotechnical units in the site, and 1/2000 scaled engineering geological map was prepared. Lugeon tests were applied for determination of bedrock permeability.

In the laboratory studies, physical and strength properties were determined on the samples collected from the boreholes and rock blocks.

      In the field, scan-line surveys on natural rock exposures were performed and the quantitative description of discontinuities was conducted.

Rock mass strength was calculated with Hoek-Brown empirical approach using by data obtained from laboratory studies and scan-line surveys.

      Engineering properties of rock masses were performed with the RMR system and stability of slopes was investigated using SMR system

During the landfill project, to describe the area to be excavated and to select suitable excavating equipments, excavatability properties of the rock masses were determined using the seismic methods and geomechanic parameters.

      It is determined that proposed landfill site, an old open pit area, is geotechnically suitable. Besides, project studies to the landfill site for Trabzon City were performed.
