Abstract

The main objective of this project was to develop correlations to determine the liquefaction potential
of loose sand deposits, using the CPTu test; for this purpose, it was necessary to determine the
behavior of CPTu tests in the calibration chamber (CC) of the Institute of Soil Mechanics and Rock
Mechanics (IBF) in Karlsruhe Institute of Technology, moreover to determine the resistance to
liquefaction by means of cyclic undrained tests for sand samples, also to establish a correlation
between the relative storage density (ID) of the sample, the tip resistance (qc) of the CPTu
and the liquefaction resistance (CRR) of the triaxial tests and finally compare the experimental
correlation obtained with existing correlations of the literature. With this project it was concluded
that when comparing the correlations for the experimental materials studied by the IBF, it was
determined that in the region of low storage densities and low peak resistances a good similarity.
However, for higher densities and, therefore, greater peak resistances, the correlation curves
for the experimental materials were flatter than in bibliographic references. In other words, the
liquefaction resistance of the experimental materials in this area is lower than what the curves of
the literature would have predicted. Finally, it is not possible to directly apply the results of this
project in any other sand deposit; since the materials of the correlations made (Kali4) and other
