Development of correlations to determine the liquefaction potential by applying the piezocone test (CPTu) in a calibration chamber (CC).

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 RockMech...

Desarrollo de correlaciones para determinar el potencial a licuefacción mediante la aplicación del ensayo de penetración estática de piezocono (CPTu) en una cámara de calibración (CC).

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.

Con esteproyecto se concluyó que en la región de bajas densidades de almacenamiento y bajasresistencias en punta una buena similitud, esto al comparar las correlaciones para los materialesexperimentales estudiados por el IBF con correlaciones provenientes de la literatura. Ahora bien,para densidades altas y, por lo tanto, mayores resistencias en punta, las curvas de correlaciónpara los materiales experimentales fueron más planas que en referencias bibliográficas; enotras palabras, la resistencia a licuefacción de los materiales experimentales en esta área esmenor de lo que habrían predicho las curvas de la literatura. Así pues, no es posible aplicardirectamente los resultados de este proyecto a otros sitios de estudio; ya que los materialesde las correlaciones realizadas (Kali4) y otros suelos difieren en aspectos como la mineralogía(criterios geológicos), la granulometría y la forma de partícula (criterios de composición); loscuales influyen sobre la susceptibilidad a la licuación. 2020-11-11 2021-06-11T01:25:57Z 2021-06-11T01:25:57Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/5482 10.18845/tm.v33i7.5482 http://hdl.handle.net/2238/13073 spa https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/5482/5203 https://creativecommons.org/licenses/by-nc-nd/4.0 application/pdf Editorial Tecnológica de Costa Rica (entidad editora) Tecnología en marcha Journal; 2020: Vol. 33 especial.
