Standard penetration test (SPT) is one of the most popular and economical field tests and its derived parameters are still extensively used for practical applications. Although the test is very popular in practice, its entire behavior during driving has rarely been depicted to date. This paper presents an attempt to simulate the entire behavior of the SPT by using the energy balance approach. The mechanism of driving SPT sampler was conceptually modeled as that of a miniature open-ended pile, which requires basic in-situ parameters of sand as input parameters. From the simulated results, a complete profile of blow counts versus cumulative penetrations can be obtained. The proposed approach was well validated by comparing the simulated results with well-documented data obtained from two experimental sites.
