Summary:

In this thesis, the engineering properties of the rocks belonging to Late Cretaceous-Paleocene

Tonya Formation were tried to determine an area in Akoluk Trabzon province which is expected to

be opened for construction. In this context, geophysical methods such as ground penetrating radar,

electrical resistivity tomography, seismic refraction tomography and multichannel analysis of

surface wave methods were applied in the study area for the first time. In total, common offset

GPR at 39 line, common midpoint GPR at 50 points, electric resistivity tomography at 11 profile,

seismic refraction tomography measurements at 9 profiles, and multichannel surface wave analysis

measurements at 10 profile were performed in two different parts in studied field. Moreover, 2

crosshole tomography models were created considering geological information and result of

geophysical methods. Geophysical-geological-geotechnical properties belonging to the study area

were determined by together evaluating the one dimensional and two dimensional images obtained

from the forward and inverse solution of geophysical data and premade drilling studies which done

in 3 points. As a result, it was seen the repetitive changes up to 15 m depth (weak unit with clayweak

competent unit with calcite- weak unit with clay) from the geophysical data and drilling

information. Deeper than these depths, the presence of component soil was observed. In addition

since the horizontal and vertical continuity of the medium is variable, the geophysical results in the

location on the soil where the building will be built should be taken into consideration in any

construction situation.
