ENERGY TRANSFER MECHANISM IN SPT
The note desctibes the study of the energy transfer mechanism during sampler penetration in the SPT (standard penetration test) using a closed-form solution for a rigid-hammer and a rigid-plastic soil-resistance function. It shows that the energy utilized for soil penetration decreases with increasing blow counts, and that several penetration cycles are required to transfer the energy at low blow counts. Solutions for the rigid-plastic model were then compared with those for an elasto-plastic model, in which it was assumed that the elastic soil compression for all blow counts is 2 mm.
