The present study, which is of an applied type, was conducted with the aim of geotechnical zoning of the soil of Ahvaz city using GIS. By collecting geotechnical information obtained from 200 drilled boreholes to a depth of 10 meters and using ArcGis, soil geotechnical parameters were zoned in Ahvaz. Factors affecting soil bearing capacity including soil adhesion, internal friction angle, and soil specific gravity were selected for zoning. The zoned interpolation map of the internal friction angle in Ahvaz city showed that with increasing soil depth, the internal friction angle has increased. With increasing depth, the internal friction angle has increased, so that at a depth of 10 meters, in most boreholes drilled in the mentioned areas, the amount of internal friction angle has increased to more than 41 degrees. The results of the adhesion zoning map based on the drilled boreholes showed that there is no statistical relationship between this geotechnical component and the depth increase. Also, the study of soil-specific gravity based on drilled boreholes and zoning interpolation map in the present study showed that with increasing soil depth, the average specific gravity increased significantly from 1.6% at 2 m depth to 47.9% at depth of 10 Meters has been reached. In general, these components, especially specific gravity, are related to determining the load-bearing capacity of the soil and can be used to assess the feasibility of choosing the best spatial option for the construction of specific projects.
