Dissipated energy in undrained cyclic triaxial tests [PDF]
, 2015 Energy-based methods are an emerging tool for the evaluation of liquefaction potential. These methods relate excess pore water pressure build-up to seismic energy dissipated per unit volume.

CYCLIC PRESSUREMETER LOADING AND LIQUEFACTION PROPERTIES OF SANDS
SOILS AND FOUNDATIONS, 2003 Based on a series of cyclic cavity expansion tests carried out on a thick hollow cylinder apparatus (HCC) and on mini-pressuremeter tests performed in a calibration chamber, a method is proposed to establish a reliable correlation between the result of a "reference" cyclic expansion test carried out in a sand, in terms of cavity volume accumulation ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Water pollution by oil and organic substances causes serious problems that threaten the ecosystem. Superhydrophobic materials represent an effective solution for removing oil from water. The present paper investigates the development of a low‐cost, superhydrophobic composite for oil–water separation.

The importance of accurate time-integration in the numerical modelling of P-wave propagation [PDF]
, 2017 The numerical dissipation characteristics of the Newmark and generalised-α time-integration schemes are investigated for P-wave propagation in a fully saturated level-ground sand deposit, where higher frequencies than those for S-waves are of concern ...

Ensemble‐based soil liquefaction assessment: Leveraging CPT data for enhanced predictions
Civil Engineering Design, Volume 7, Issue 1, Page 23-35, March 2025.Abstract This study focuses on predicting soil liquefaction, a critical phenomenon that can significantly impact the stability and safety of structures during seismic events. Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk ...

Experimental Study on Mechanism of Wave-Induced Liquefaction of Sand-Clay Seabed
Journal of Marine Science and Engineering, 2020 In this study, a series of laboratory experiments for the response of wave induced clay-sand seabed were carried out to clarify the mechanism of liquefaction of clayey seabed. The experiments were conducted in an 80 m long wave flume.

An energy-based interpretation of sand liquefaction due to vertical ground motion
, 2017 In several recent earthquakes, high vertical ground accelerations accompanied by liquefaction were observed. Downhole records have also shown that large vertical accelerations do not necessarily originate from the source, but rather get amplified towards
