This study area located in HoNam High-Speed railway soft ground section. So it carried out the boring survey, field survey and test of laboratory. It collected the engineering data of ground and the data for the establishment arrangement. The investigation did a soil investigation in Nonsan. The investigation item excuted seismic piezocone penetration test, s-wave seismic refraction survey, ps logging test, density logging test which is a physical exploration and boring. Eventually, results of geotechnical and shear-wave survey are useful for ground information in soft ground that has identified the characteristics of geological responses and elastic modulus.
