Abstract
Liquefaction is an effect for which a saturated soil suffers a severe loss of shear strength due to an increase of pore-water pressure. This effect, which generally affects loose granular soils, is usually produced by cyclic loading such as that the induced by earthquakes. In Spain, three different national standards plus Eurocode can currently be applied in the assessment of potential liquefaction of a soil site. In this research, a comparative study of the similarities and differences between these standards has been performed. Moreover, to improve understanding of the differences between standards, the factor of safety against liquefaction has been obtained for three real cases in the province of Alicante. According to the obtained results, it can be concluded that the safety factor can present significant differences depending on the code used.
Keywords: Liquefaction, NCSE- 02, NCSP-07, ROM, Eurocode.
