Abstract
The article puts forward a procedure to determine structure and physico-mechanical properties of near-surface cohesive soil based on seismic surveying. The backbone of the approach is the use of distribution of P- and S-waves obtained from combination of the seismic refraction technique modification and the multi-channel surface wave analysis. The recovery of the physico-mechanical properties uses correlation dependences. The authors give an example of field data processing. The field research covered a section of a motor road where groundwater level is determined and zones subjected to washout and deformation are detected.
