Abstract
In this study an attempt has been made to develop correlation between standard penetration test (SPT) N values and low strain shear modulus (Gmax). The field experiments of Multichannel Analysis of Surface Wave (MASW) are carried out at 38 locations close to boreholes having Standard Penetration Test N values and in-situ density. These experimental data were generated and used for seismic microzonation of Bangalore, India. In-situ densities of subsurface layers were obtained from undisturbed soil samples collected from the boreholes. Shear wave velocity (Vs) profile with depth were obtained for the same locations or close to the boreholes using MASW. The low strain shear modulus values have been calculated using measured Vs and soil density. About 215 pairs of SPT N and shear modulus values are used for regression analysis and correlation between them are developed. The differences between fitted regression relations using measured and corrected N values were analyzed and presented. More details of correlation between shear modulus versus measured and corrected SPT N values and comparisons are presented elsewhere.
