Abstract
The routine point-based geotechnical site testing for assessing the bearing capacity of near-surface soil masses in major civil engineering construction sites succeeds in simple 1-D geological situations. However, the Multichannel Analysis of Surface Waves (MASW) method is routinely used in geotechnical engineering, which determines the shear wave velocity variation with depth. Earlier, our regression analysis based on the geoelectric imaging methods of electrical resistivity tomography (ERT) and induced polarization imaging (IPI) along with point geotechnical tests predicted 2-D geotechnical test results. Our prediction method is based on site-specific validated regression equations describing actual correlations of geo-electrical and geotechnical data and site-independent well established empirical relations of Standard Penetration Test, SPT ‘N’ with different formation and geotechnical parameters.
