THEORETICAL AND EXPERIMENTAL INVESTIGATION ABOUT THE LAGOON CLAYS OF THE KONYAALTI REGION IN ANTALYA
Abstract
Konyaaltı coast area is a famous touristic region with its 9 km long beach at the west side of Antalya City. Nowadays, the region is subjected to multi - storey and dense constructioning activities due to its touristic charm. Lagoony and alluvial mechanisms in its development, the soil profile presents a considerably complex structure as a result of sea level and vertical ground movements. In this study, geotechnical and mineralogical characteristics of blue – green clays of the Harbour District existing inside the boundaries of Antalya Konyaaltı Municipality were investigated with comprehensive field and laboratory tests. The geological and mineralogical properties of the sediments constituting the alluviums of this region were investigated and the distribution of the clay minerals was presented. The strength and the compressibility characteristics of the soil were defined with some correlations obtained by the laboratory and field test results. This aim, undisturbed and disturbed soil specimens were taken from 12 drilled boreholes at 1.5 m intervals down to 30 m depths by using Shelby tubes in order to determine the soil profile and the geotechnical properties. In addition, SPT (Standard Penetration Test) tests were carried out in all the boreholes. Besides the Mesozoic old units seen at the base of the region, the travertines of Quaternary units, side remains, beach deposits and alluviums exist at the top. The unconfined compressive strength (qu), undrained cohesion (cu), compressive index (Cc) of the soil vary between 20 kN/m2 and 84.2 kN/m2, 7.0 kN/m2 and 90 kN/m2, 0.095 and 0.38 respectively.
