Abstract
The objective of the study is to produce digital geotechnical maps of Najaf city and Kufa through employing the capabilities of GIS techniques. Those maps can represent the distribution of different geotechnical properties in an accurate easy to use manner.
This study provides an easy method to analyze the spatial information and the link between them to give an overview of the geographic location and characteristics of comprehensiveness , as well as to extract information from (DTM) the new through the original information on the map such as extract contour maps. In this research data has been taken on some of the properties of the soil to the Najaf city and Kufa, bearing capacity, layer description, dry soil density, wet soil density, chemical tests of the soil, where they include values and concentrations both of: (organic matter , SO3, Gyp and TSS (Total Soluble Salts)) and analysis of this data using GIS to produce maps with contour.
Thedata included the properties of the soil for (181) boreholes with depth (15m) distributed randomly on residential areas in all districts of the Najaf city and Kufa .
The most important conclusions in this study were the bearing capacity ranged between (3.0-22.0T/m2). Soil of Najaf city and Kufa was being in the form of layers and these layers were composed of: sand, clay, gypsum and silt in various percentage which randomly distributed at different depths and the water table is seasonally variable. The use of the software (GIS) in linking the geotechnical properties of the soil is useful in reducing the time, cost and effort, as well as considered as a tool to help when a conventional soil being investigated.
