Energy Measurement in Standard Penetration Tests
Sustainability, 2023 The standard penetration test (SPT) is a widely used in situ test method worldwide that can evaluate soil properties based on the blow counts (N-value). The N-value depends on soil properties, and the energy transferred to the drill pipe during hammering. Currently, European and American scholars generally believe that variation in the amount of hammer

Estimation of deformation modulus of gravelly soils using dynamic cone penetration tests
Ain Shams Engineering Journal, 2013 Estimating the deformation modulus of gravelly soils is a challenging task. The estimate of deformation modulus of cohessionless soils in general relies on availability of correlation between in situ test parameters and deformation modulus back ...
