Determinação da liquefacção de solos a partir de ensaios CPT
DETERMINATION OF LIQUEFACTION TRIGERRING FROM CPT
The current state of the practice for evaluating liquefaction triggering is to
calculate the cyclic stress ratio and the cyclic resistance ratio from correlations with
either the standard penetration, cone penetration, shear wave, or Becker penetration
field tests. Determination of the amount of lateral spreading that occurs is based on
empirical correlations with observed field data. This paper reports the results of a
research study to investigate the effect of liquefaction triggering with field data, namely
the cone penetrometer test. This research involved centrifuge testing utilizing a
miniature cone penetrometer system suitable for testing in -flight.
