LIQUEFY2 implements the "1997" NCEER SPT procedure for liquefaction triggering analysis summarized in a paper by Youd and Idriss (1997).  The program user selects magnitude-scaling factors, SPT-correction factors, fines-content adjustments, and the new CRR base curve to compute the factor of safety against liquefaction triggering.  The program allows for the use of different groundwater levels for the analysis and for the field boring.  Also, it can estimate the beneficial effects of increased vertical stresses caused by the addition of compacted fill over the top of a liquefiable soil profile.
