Abstract
A standard penetration test (SPT) is one of the in-situ tests conducted for onshore and near shore soil investigation projects. SPT test data are extensively used for estimation of soil design parameters needed for geotechnical analysis. However, quality and reliability of SPT results are, very often, not satisfactory due to various reasons such as variable height of fall of hammer, inclination of driving rods, improper release of hammer resulting in partial energy transfer. A study is carried out to determine SPT hammer efficiency for different hammer operating systems being used in India. SPT hammer energy measurements were carried out at three project sites using different SPT hammer operating system. This paper summarizes ways to improve quality of SPT test results and presents the results of energy measurements made using “SPT Analyser.”
