Investigation of Erzincan Airport Landing Field with GPR Method

In this study, it is aimed to visualize whether the deteriorations observed from surface on the landing surface of the aircraft at the Erzincan Airport floor is continuing horizontally and vertically under the floor with GPR data. It is useful to do modeling exercises to help comment on the soil structure from the radargrams obtained. Primarily, GPR data were collected using a 800 MHz central frequency antenna. GPR modeling studies have been carried out with the finite difference time method (FDTD) in the time by obtaining from the construction project for the ground structure in the inspection area. By comparing the obtained real field data with artificial radargrams theoretically generated, the deteriorations of ground structure was determined. From the results obtained; It is observed in radargrams that ground quality is generally in good condition and ground is composed of four different units although fractures and deterioration are observed in places. It was also observed that fractures observed from the surface at 3 and 15 meters along the measurement line extended to depths of about 35 cm in the ground. In addition, in theamplitude slice maps of different depths, the lateral extensions of the fractures were also determined.
