ABSTRACT
To perform a quick preliminary geotechnical survey, modern non-destructive methods can be used. One of those is the Multi-Channel Analysis of Surface Waves (MASW) allowing constructing a wave section for distribution of shear-wave velocities in the layering studied within a short time and with minimum costs. Based on the obtained velocities, the initial shear modulus at small deformations can be estimated. However, to assess deformation characteristics of soils, deformation moduli are required, and a direct method to determine those in the field is plate load testing. That is why the purpose of the study is to determine a correlation dependence between the deformation modulus obtained from plate load tests and the shear modulus determined based on wave analysis data using the MASW method. The tests were conducted for various types of dispersive and semi-rocky soils at five sites of Perm Krai, Russia. A dependence between results of the plate load tests and results of the wave analysis using the MASW method was established. The dependence allows determining the deformation modulus of soil and conducting a geotechnical survey of a foundation base within a short time.
