Insights into the assessment and interpretation of earthquake-induced liquefact...

Earthquake-induced liquefaction is a prominent and impactful natural hazard responsible for substantial economic losses worldwide. Hence, engineers and researchers are currently interested in developing methods and techniques to mitigate this destructive phenomenon. Reducing the degree of saturation is a reliable method to improve the liquefaction resistance of sandy soils since it directly influences the pore ...

Liquefaction assessment based on numerical simulations and simplified methods: ...

The accurate estimation of earthquake-induced liquefaction damage requires detailed ground response analysis, which does not generally consider liquefaction. This paper presents a well-documented pilot site where different approaches to estimate surface ground motion were compared. A simplified stress-based method and non-linear dynamic effective stress numerical analyses were used to identify liquefaction. HVS...

Liquefaction resistance of TP-Lisbon sand: a critical state interpretation usin...

This paper describes a comprehensive characterisation of liquefaction resistance of a sandy soil collected from the 'Terreiro do Paco' in the historical centre of Lisbon (Portugal), denominated as TP-Lisbon sand. This natural sand has experienced earthquake-induced liquefaction caused by the 1755 earthquake. The characterisation was carried out by combining in situ with laboratory tests. The results of in situ ...

Small-strain stiffness of liquefiable sands: a comparison between bender elemen...

Liquefaction and undrained cyclic behaviour in fully and partially saturated sands

Improvement of cyclic liquefaction resistance induced by partial saturation: An...

Methods to estimate the liquefaction resistance in sandy soils have been proposed in the literature, involving correlations between cyclic resistance ratio and seismic wave velocities measured by in situ and laboratory tests. However, the applicability of these correlations has not been validated in sands improved with the induction of partial saturation. This study addresses the assessment of cyclic liquefacti...

Modelling the critical state behaviour of granular soils: Application of NorSan...

The soil behaviour can be represented by numerical modelling of element testing using diverse constitutive models. However, not all constitutive models allow the simulation of the stress-strain response at the critical state in granular soils with both contractive and dilative behaviour. Moreover, the accuracy of these models depends highly on the quality of the experimental data used for their calibration. Thi...
