Published in 2020 at "Engineering Geology"

DOI: 10.1016/j.enggeo.2019.105347

Abstract: The paper presents a simplified approach to determine the post-cyclic deformation of liquefied sloping grounds. The approach uses instability curves derived from undrained multi-stage (cyclic+monotonic) triaxial tests. It is shown that the salient aspects of… read more here.

Published in 2020 at "Journal of Rock Mechanics and Geotechnical Engineering"

DOI: 10.1016/j.jrmge.2020.01.007

Abstract: Abstract To investigate the post-liquefaction shearing behaviour of saturated gravelly soil, laboratory tests were conducted using a static-dynamic multi-purpose triaxial apparatus. In addition, numerical simulations using the discrete element method (DEM) were performed to preliminarily… read more here.

Published in 2017 at "Soils and Foundations"

DOI: 10.1016/j.sandf.2017.10.001

Abstract: Abstract Buildings and infrastructure suffer extensive damage due to liquefaction during strong earthquakes. The FL method has long been considered adequate for evaluating the likelihood of liquefaction, and is widely used. Due to the high… read more here.

Published in 2021 at "Soils and Foundations"

DOI: 10.1016/j.sandf.2021.06.009

Abstract: Abstract The estimation of strength deterioration with the increase in the undrained cyclic shear-induced strain in liquefiable soils is an important topic in geotechnical earthquake engineering that is still poorly understood and needs to be… read more here.

Published in 2021 at "Soils and Foundations"

DOI: 10.1016/j.sandf.2021.09.002

Abstract: Abstract In this study, we performed undrained cyclic–torsional–shear tests on clean and silty sands to examine post-liquefaction volumetric strain. Accordingly, we proposed a novel density index—ultimate volumetric strain—to evaluate the density of clean sand and… read more here.

Published in 2020 at "Soil Dynamics and Earthquake Engineering"

DOI: 10.1016/j.soildyn.2020.106288

Abstract: Abstract The Liquefaction Experiments and Analysis Projects (LEAP) provides an international collaboration platform to assess key aspects related to seismic induced soil liquefaction. Within this scope, the current study investigates the influence of dilatancy and… read more here.
