CANO-FRANCO, Valentina et al. Analysis and experimental validation of soils liquefaction through granulometric study. Dyna rev.fac.nac.minas [online]. 2023, vol.90, n.225, pp.164-171.  Epub Jan 13, 2024. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v90n225.105204.

Liquefaction phenomenon is a problem related to soil conditions that can entail a high risk for civil infrastructure and people, and therefore requires an adequate understanding of its causes. The present work analyzes the influence of the granulometry of the soil material on the occurrence of liquefaction. For this purpose, a laboratory assembly of a block structure supported on different types of soils, which is subjected to controlled seismic movement by means of an electromechanical platform, was developed. The results show that medium sands contribute to the presence of the phenomenon, while fines and gravels act as mitigators. In addition, classification criteria were defined to determine the liquefaction levels and the affectations presented by the structure due to the phenomenon.

Keywords : soil liquefaction; soil granulometry; sand; earthquake; soil prototype.
