| Descripción: | The main objective of this project was to develop correlations to determine the liquefaction potentialof loose sand deposits, using the CPTu test; for this purpose, it was necessary to determine thebehavior of CPTu tests in the calibration chamber (CC) of the Institute of Soil Mechanics and RockMechanics (IBF) in Karlsruhe Institute of Technology, moreover to determine the resistance toliquefaction by means of cyclic undrained tests for sand samples, also to establish a correlationbetween the relative storage density (ID) of the sample, the tip resistance (qc) of the CPTuand the liquefaction resistance (CRR) of the triaxial tests and finally compare the experimentalcorrelation obtained with existing correlations of the literature. With this project it was concludedthat when comparing the correlations for the experimental materials studied by the IBF, it wasdetermined 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 curvesfor the experimental materials were flatter than in bibliographic references. In other words, theliquefaction resistance of the experimental materials in this area is lower than what the curves ofthe literature would have predicted. Finally, it is not possible to directly apply the results of thisproject in any other sand deposit; since the materials of the correlations made (Kali4) and other |
