Following is
the list of more than 240
methods and formulae for correlation of geotechnical engineering
soil properties from SPT blow counts (N60 or N160), which are all incorporated into
NovoSPT program. We are continuously improving our products, so
please come back later and check this updated list of implemented
methods and download the latest version.
User may select those correlation methods which are expected to be
compared and plotted on the graph.
