Using 2D Electrical Resistivity Imaging to Evaluate Soil Investigations in Palm Towers Site of Al-Muthana Airport, Baghdad, Iraq

For engineering site investigations at Al-Muthana Airport land in Baghdad, Iraq, the two-dimensional electrical resistivity imaging method was used. The investigation is important for figuring out subsoil profile, weak spots, and groundwater level of possible production sites area. Wenner-Schlumberger array used to survey six spreads with a total length 600m, 100m acquired each line, distance 1m between electrodes. depth 23.5 surveyed line. Robust inversion model techniques showed that values resistivities were not all same inverted models. Based on models, found be 3 – 4 meters first about 4.5 second site, which 1 m deeper than what geotechnical report. Further, top 1-1.5 sediments have different components, hardness, moisture levels. So, current study stated this layer should picked up compacted before foundation built. Far down 1.5m, seems wet, so low permeability must added around foundation.
