The importance of geological - geotechnical studies in planning and the Karapınar (Konya) OIZ example

Abstract

With the industrial revolution, an uncontrolled migration wave from rural areas to large cities occurred. The sudden increase in population density in cities caused the formation of unplanned and uncontrolled areas. Due to the increasing population, consumption increased, the demand for equipment required to facilitate daily life and increase life comfort increased, industrialization grew rapidly to meet these consumption needs and the demand for new industrial areas and raw materials increased in parallel with the growth. In countries where socio-economic developments are intense, it has become a necessity to direct and develop industries within the framework of specific plans and programs. Due to these sudden and rapid developments, planned industrial facilities and specialized industrial zones have increased in importance as much as planned urban areas. Organized Industrial Zones are important for the development of industry in order to solve regional imbalances. In Karapınar Organized Industrial Zone (OIZ), it is aimed to determine the geological characteristics of the selected area together with the selection of the location, and to determine the soil groups and soil index parameters of the examined area before planning, and to make planning in accordance with these soil groups. In areas planned without determining the characteristics of the soil types, material losses as well as moral losses occur due to faulty planning originating from the characteristics of the soil, especially due to different settlements. In order to prevent design errors originating from the characteristics of the soil and to realize more functional plans, determining the soil index and parameters of the region is among the design factors. As a result of this study, the soil generally consists of fine-grained silt-clay, silt-fine sand alternation. Within this unit, gravelly coarse sand transitions were observed in the form of lenses. Although the soil in the study area is generally composed of CH, CL group clays, it was understood that CH group cohesive soil is more common.
