N-SPT and Transverse Resistance Correlation Using SPT and Geoelectric Data in Gunung Anyar

Summary Traditional geotechnical approach for identifying basement soil in construction usually done by using borehole method such as Standart Penetration Test (SPT). SPT measures the soil strength by counting the number of blow of the device for a standart penetration to happen. SPT method is very useful in general for measuring the soil strength of a point, but it faces some disadvantages and difficulties. So, thisresearch correlate the N-SPT and Transverse Resistivity of two borehole and two VES data obtained in Gunung Anyar Regency, Surabaya. The correlation shows a minimal error with correlation value of 0.9008 and 0.8199. This results may help further research for consideration of VES substituting traditional SPT method for geotechnical application.
