Abstract

The influence of earthquake magnitude upon the commonly used correlation between Standard Penetration Test (SPT) blow count and liquefaction potential is evaluated using a probabilistic model for pore pressure development during seismic loading. The analysis evaluates the probability of initial liquefaction given an event magnitude and a normalized SPT blow count. The correlation between SPT resistance, stress ratio, and magnitude is investigated by plotting contours of constant probability of initial liquefaction. The contours predicted by this proposed model is compared with the recommendations of Seed, Idriss, and Arango. Results indicate that these previous investigators may have overestimated the influence of earthquake magnitude in developing their correlation.
