Resistivity Correlations with SPT-N and Shear Wave Velocity for Patna Soil in India
https://orcid.org/http://orcid.org/0000-0003-1356-473X
The paper develops the resistivity correlations with standard penetration test (SPT)-N and shear wave velocity (Vs) for the soil in Patna region in India. As part of the investigation, 16 numbers of each SPTs and electrical resistivity tests (ERTs) were conducted in the study area of 500 acres. The field tests were conducted up to a depth of 20 m, uniformly spanning across the study area. During the SPT, soil samples were collected at selected depths for the laboratory investigation. ERTs were performed using the Schlumberger array. Field test results were used to develop the correlation between resistivity and SPT-N. Previously available shear wave velocity data of the area were used for the developing the correlation between resistivity and shear wave velocity. The results revealed the existence of a strong linear correlation between resistivity and SPT-N. A relatively weak linear correlation was observed between resistivity and shear wave velocity. Further, the resistivity correlations were extended to corrected SPT-N and moisture content for the given soil. In overall, the developed correlations are useful for the quick determination of the soil design parameters solely performing electrical resistivity tests, saving the time and effort required by conventional tests.
