Application of 2D Electrical Resistivity Method for Detections of Subsurface Karst Hazards Within the State Company for Glass and Refractories in Ar-Ramadi City, Iraq

Abstract

The electrical resistivity method has been applied to detect the subsurface karst hazards using Dipole-dipole and Wenner – Schlumberger arrays with a-spacing equal to 1m and n-factor 6 at three selected stations within the State Company for Glass and Refractories in Al-Ramadi City, Iraq. The results indicate that the area formed a weakness zone as two separated zones, the first at a depth in the range of 2.5-5 m within the quaternary deposits and the second weakness zone within the Injana Formation deposits at an approximate depth range of 7 – >12 m. The investigation advises conducting physical, chemical, and engineering site investigations to decide the suitable treatment techniques to solve these problems.
