Studies of surface improvement have been carried out in Georgia-Poti in order to decrease surface deformations since surface conditions of railway line that comes from the harbor are too poor. Stone column and jet grouting methods were evaluated together as surface improvement methods. As engineering parameters on the surfaces which are applied, jet grouting are higher than the other method, it was decided to improve the line within project with this method. This study was carried out in order to present surface parameters obtained with seismic refraction data carried out together with surface improvement practices. Findings show that parameters of shear wave velocity, amplification rate and bearing power obtained with jet grouting practices are higher than those of stone column practices.


Key words: Jet grouting, seismic refraction, soil improvement, stone column.
