Development of nondestructive techniques for preliminary soil foundations geotechnical assessment

Abstract

Modern nondestructive techniques of wave analysis can be applied for the express preliminary geotechnical soil assessment. One of them is Multichannel Analysis of Surface Waves (MASW) which allows obtaining velocities profile of shear waves and the initial shear modulus for the upper section promptly and at minimal labor costs. But for soil deformation properties assessment the deformation modulus obtained by the direct technique of plate load test (PLT) is required. The purpose of the performed study is an assessment of the correlation between the PLT deformation modulus and the initial shear modulus obtained via MASW.
