THE APPLICATION OF GPR IN DETECTING THE FAST FEED SUPPORTING TOWER FOUNDATION

摘要

The Five-hundred-meter Aperture Spherical Telescope (FAST), which is a major national scientific project, is sited in Pingtang county of Guizhou province. The geologic structure of this location is complex and the engineering geology condition is rather severe. According to the construction plan of the FAST, six feed supporting towers will be built in a circumference of 600 meters in diameter, to function as the main load-bearing spots. In order to effectively evaluate the stability of the foundation towers and manage the engineering geology diseases, we study the Ground Penetrating Radar (GPR) samples from the FAST feed supporting tower foundation, and show that the geophysical exploration technique plays an important role in Karst foundation detection.
