Detection of Cavities and Weak Zones underneath the Break Pressure Tanks at An-Nuwfaliyah, Libya

Fathi A. Swaid and Khaled Elmahishi
Abstract—Existence of cavities and weak zones on chalky limestone and gypsum was explored in an underneath break pressure tanks by using Ground Penetrating Radar (GPR) method even the geotechnical method was used. Therefore, three different frequencies range of ground penetrating radar were used in order to cover different depths under the tanks foundation. The GPR survey pinpointed the positions of many anomalies which exist underneath tank (Ι). The anomalies can be a cavity or a type of formation of high reflection of signal indicating unfastened type of formation which may turn to a cavity at any time. However, the geotechnical result which represented in drillings at selected locations confirmed the existence of these cavities nearby or extending underneath tank (Ι) at the depths of 1 m to 5.0 m.

Index Terms—Ground penetrating radar, break pressure tanks, cavities, an-nuwfaliyah.
