Procedure and evidence of seismic research into physical properties of cohesive soils

Abstract

The article puts forward a procedure to determine structure and physical properties of nearsurface 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 multichannel surface wave analysis. The recovery of the physical 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.
