Correct Blow Counts is a program designed to assess the liquefaction potential of soil using widely published methods and the N-Value from the SPT. The program corrects the N-Value obtained in the field from the SPT and corrects it for overburden pressure, hammer energy, drill rod length and sample liner type. This value is compared to the cyclic stress ratio corrected for earthquake magnitude. The program can also be used to correct N-Values for overburden pressure only. The program only supports English Units. This is a limited trial version of the fully operational program.
