Web12 Apr 2024 · The SPT can have too much power for soft/firm clays at shallow depth, under-estimating their strength It can have too little power at depth in deep boreholes/probes, due to attenuation of torque down the rods. This can result in an over-estimation of strength of materials at depth There are several factors that will contribute to the variation of the standard penetration number, N, at a given depth for similar soil profiles. These factors include SPT hammer efficiency, borehole diameter, sampling method, and rod length factor. It therefore became evident that if the test data were to be … See more The blow counts for an SPT test at a depth of 6 m in a coarse-grained soil at every 150mm are 9, 16, and 19.
