Detection of subsurface pipes by using ground penetrating radar (GPR)‎ in selected area at University of Baghdad

الملخص EN

In this study (250 and 500)MHz antennas frequencies were used to perform eleven profile approximately perpendicular to the expected pipes at two areas to get the best subsurface picture.

In the first area there are five profiles were chosen for interpretation, the pipe was found nearly at a depth of about 1.50m.

in a location (4.14m.- 5.43m.) from the beginning of the profile using 250 MHz antenna, while it was found at a depth of 1.50m in a location 4.11m.- 4.76m.

using 500 MHz.

The second area (stadium) there are six profiles were chosen for interpretation , the pipe was found nearly at a depth of 1.30 m in a location 17.69m- 23.85m.

from beginning of the profile using 250 MHz, antenna.

while the pipe depth was about 1.30m.

and its location was found to be between 18.6m.–21.45m.

for 500 MHz .The results showed that the pipes were located at different depths and that they incised the study areas in slanted manner, and the results that have been reached in this research are differ with the engineering maps of the University of Baghdad with a slight difference of (2) meters.
