GEOTECHNICAL STUDY OF BAGHDAD SOIL

This paper comprises the study and analysis of Baghdad soil for 23 geotechnical properties which were extracted from field tests of 630 boreholes with depth taken to 30m and representing 200 sites. Soil investigation reports are collected from different laboratory tests. The soil layers were divided into each 2m, which means 15 studied layers and the soil properties values were adopted and submitted in tables and digital maps to represent the variation of soil properties values with depth and relationships between the properties values. Different softwares and tools were implemented for digital maps preparation. The results clarify that Baghdad upper soil layer is mainly fill with poor strength. The stratum is erratic and non-homogenous with water levels near the natural ground surface. Baghdad soil is generally alkaline with high concentration of sulphates in the upper layers
