    Abstract

    Shear modulus (G) and shear wave velocity (Vs) of soil are important parameters to assess the dynamic soil responses for roads and highway embankments and foundations of many geotechnical structures. Borehole explorations that normally performed to measure the dynamic soil parameters in situ is time consuming and costly. Surface wave analysis is used as an alternative to obtain near surface soil profiles as a non-destructive method in soil characterization. Shear modulus G and shear wave velocity Vs of near-surface soil can be obtained through the dispersive characteristics of Rayleigh waves. The Spectral Analysis of Surface Waves (SASW) testing uses two sensors to measure phase velocity in the frequency domain from the phase shift of seismic signal. Multi-channel Analysis of Surface Waves (MASW) method is an improvement by increasing the number of geophones in the acquisition of seismic signals. However, it was somewhat difficult to obtain Vs profile through analysis of seismic records of multiple geophones. Tests have shown that soil electric resistivity measurements aremore reliable in near surface soil characterizations. This paper demonstrates how soil Vs profile is obtained using soil electric resistivity measurements. Correlations are developed between Vs and soil resistivity profile to assess near surface soil properties. Soil resistivity ration between two adjacent layers is proposed to obtain more accurate outcomes in multilayer soil resistivity model. Obtaining Vs from soil resistivity method is also simpler to perform compared to Standard Penetration Test (SPT) and others such seismic methods.
