Özet

The world is a living organism that keeps going to its precession. The natural events like earthquake, volcanic eruption and landslide are evidence of this motion. These events are defined as “natural” in areas where there is no loss of life and also property, but if there is any loss they are named as “disaster”. It is a fact that if the human could understand the language of nature and act according to science; these natural events will not turn into a disaster. For this reason; geological, hydrogeological, engineering geological and geotechnical models of the region must be accurately identified when selecting the site for engineering projects. Landslides are common problems in both residential and transportation projects. Many factors predict potential landslides such as topography, geology, vegetation and water condition. A proper geotechnical investigation before construction could protect nature; save time and money and no loss of life will happen. A landslide has occurred on the D400 road which provides transportation between Antalya and Kumluca on February 28, 2018. Fortunately; there was no loss of life, there have been taken precautions and transitions have been blocked. The landslide starts from neritic limestones and ends in the old colluvium material. Triassic aged claystone, sandstone, siltstone, limestones and Cretaceous aged ophioliticmelange are observed at the bottom. The main aim was to understand the mechanism of the landslide. Therefore, besides the topographical characteristics of the region; the engineering and geotechnical properties of the lithological units and the water condition were examined. The landslide analysis was performed by the GEO5 software program, using the obtained engineering and geotechnical parameters. The determination of engineering geological and geotechnical properties is very important in site selection for engineering structure. The engineering and geotechnical research procedure performed in the stability analysis is explained through Candır formation, in this study.
