Abstract
Today, geotechnical studies are an integral part of any development project, and having sufficient information about the depths of soil without conducting soil mechanics studies is not possible. The proper design of the structures requires the application of appropriate amounts of soil capacity, this is not possible with the geotechnical information obtained from the drilled boreholes. Therefore, in this research, geotechnical parameters have been collected in Bandar Abbas by collecting geotechnical data from 241 drilled boreholes to a depth of 15 meters. Using geological information system software (ArcGis), geotechnical parameters are zoned. This zoning provides a very good approximation of the geotechnical parameters of the soil to the engineers, which can be used in the design of the pion. The results obtained in this study show that more than 85% of the study area has coarse-grained soil layers with a moderate and dense density of sandy sand, which, by increasing the depth, especially from 10 meters below, to the density of soils They are added in the group of dense soil soils. On the other hand, the general soil layers are 6 m below and saturated with a maximum natural moisture content of 30%. Regarding the dominant soil of the region and the need to consider the geotechnical hazards in the design of the plies, zoning maps of the coefficient of reliability versus liquefaction are also provided.
