Entry: Standard Penetration test
URI: https://data.geoscience.fr/ncl/Proc/91
The standard penetration test aims to determine the resistance of soils at the base of a borehole to the dynamic penetration of a split barrel sampler and the recovering of disturbed samples for identification purposes (SPT). It consists in driving the sampler by dropping a hammer of 63.5 kg mass on to an anvil from a height of 760 mm. The number of blows (N) necessary to achieve a penetration of the sampler of 300 mm is the penetration resistance.
