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.

Liquefaction Potential of Silty Sand in Simple Shear [PDF]
Mehran University Research Journal of Engineering and Technology, 2013 In this paper, the liquefaction potential of medium dense and dense sand layers was studied by performing constant volume (undrained) cyclic simple shear tests using cyclic simple shear apparatus. Strain-controlled approach was adopted.

Liquefaction resistance of MICP-treated calcareous sand with different particle size and gradation
BiogeotechnicsCalcareous sand is a type of marine soil with the poor engineering performance and a high potential of liquefaction under seismic or wave action. To address this issue, microbially induced calcium carbonate precipitation (MICP), an eco-friendly bio ...

Study on Seismic Damage Mechanism of Dredger Fill Ground in Tianjin Binhai Area [PDF]
E3S Web of Conferences, 2021 Tianjin binhai new area has a large area of dredger fill groud, And it is easy to produce dredger fill seismic settlement and saturated sand liquefaction under earthquake action. We simulate seismic subsidence state of Dredger Fill and liquefaction state

Post-liquefaction reconsolidation of sand [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 Loosely packed sand that is saturated with water can liquefy during an earthquake, potentially causing significant damage. Once the shaking is over, the excess pore water pressures that developed during the earthquake gradually dissipate, while the surface of the soil settles, in a process called post-liquefaction reconsolidation.

Rock and Soil Mechanics, 2021 Most of the constitutive model for liquefaction analysis cannot simulate the large post-liquefaction deformation of saturated sand, and there is little research on the nonlinear time-domain large deformation constitutive relationships suitable for ...
