Utilizing ERT and GPR to Distinguish Structures Maleficence the Constructions in the New Administrative Capital, Egypt

Abstract

The new administrative capital (NAC), as decided by the Egyptian government's proposed planning, is placed 45 kilometers east of Cairo. According to Egyptian government strategies, this city will be the country's future governmental and economic hub. Ministries, crucial government agencies, and sectors are all expected to be represented on the site. The future capital's total land area is around 700 square kilometers. It is projected that there are five million people living there, this population could rise to seven million people. The skyscrapers sector in the New Administrative Capital is the subject of the research. To detect near-surface structures at the chosen building site, nine Electrical Resistivity Tomography (ERT) profiles and twenty-four Ground Penetrating Radar (GPR) profiles were used in this study. After the necessary and appropriate processing, the results that extrapolated from all measured profiles of both tools, demonstrated that the research region can be separated into two different shallow layers. The (Higher Miocene) sandy limestone rock makes up the main first surface layer with thickness about 4 meters. The second layer consists of silty shale rock with thickness about 12 meters in some places. This The most obvious features that had an impact on building were normal faults in the WNW and ENE directions, with minor fractures between them, as well as a few shale lenses can reach diameters of 3 to 4 meters. Additionally, the retrieved findings from the two geophysical tools demonstrate that the shape and thickness of the inferred layers are in satisfactory correlation.
