Production of geotechnical maps of the south-west of the city of Kirkuk using geographic information systems

Abstract

After the Urban Development and urbanization of Kirkuk city in the past two decades, it has become necessary to turn to modern technologies to study the geotechnical properties of soils, and geographic information systems meet this necessity. The main objective of the study was to create geotechnical maps of the southwestern quarter of Kirkuk city, which is bordered by the private river to the East, Al-Badr neighborhood to the west, al-Quds neighborhood to the North, and the University neighborhood to the South, which particularly saves the cost of soil tests, time, and provides a quick source of information necessary for engineering projects. Geotechnical maps are widespread nowadays due to the presence of geographic information systems (GIS) the maps in this depth study were created by the ArcGIS program using the IDW method. In this study, (17) samples were collected to determine the characteristics that were determined for the study and to classify the soil to subsequently assess the permissible bearing capacity. The results of geotechnical examinations of the soil and the resulting maps to a depth of (2m) showed that the study area is dominated by alluvial soils with low plasticity with small areas of gravel soil north of the study area and small areas of clay soil south of it. The moisture content is between (1. 8% -16. 9%), the plasticity limit is between (0% -26%), the liquidity limit is between (0% -48%), the plasticity index is between (0% -26. 6%).
