Shaking table test on underwater slope failure induced by liquefaction

Soils and Foundations, 2023
Sand liquefaction is a process in which the excess pore water pressure of saturated sand soils increases and the effective stress of saturated sand decreases under the action of vibration, resulting in the transition of sand soils from the solid state to

Numerical Modelling of Multi-directional Earthquake Loading and Its Effect on Sand Liquefaction [PDF]

, 2015
Earthquakes generate multi-directional ground motions, two components in the horizontal direction and one in the vertical. Nevertheless, the effect of vertical motion on site response analysis has not been the object of extensive research.

Nonsilting transport characteristics of coal slurry in a deep underground fluidization conveying pipeline under the action of a guide vane swirler

Deep Underground Science and Engineering, EarlyView.
Aiming at the scientific frontiers of in situ fluidized mining of deep resources, a deep coal fluidized pipeline lifting system based on hydraulic conveying has been proposed. To solve the issue of particle sedimentation of large particles in horizontal connection sections, a solution involving the installation of guide vane‐type swirlers in the ...

Experimental study on mechanical properties of gassy sand with high degree of saturation and state-dependent constitutive modeling

Yantu gongcheng xuebao
The special existence of gas in gassy sand makes its basic properties different from those of general unsaturated soils. To analyze the undrained mechanical properties and static liquefaction instability of gassy sand, this work extends the triaxial test

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.

Liquefaction and post-liquefaction properties of sand-silt mixtures and undisturbed silty sands

Soils and Foundations, 2019
Abstract Severe damage to earth structures mainly consisting of fine sands containing non-plastic silt has often occurred due to the liquefaction of the fill materials. However, the changes in the liquefaction susceptibility and post-liquefaction undrained behaviour of fine sands associated with the increase in the amount of non-plastic silt have not

Maintaining egg freshness in the absence of refrigeration: The potential of zero‐energy cooling pots

JSFA reports, EarlyView.
Abstract Background Egg storage in regions with unreliable electricity is challenging, leading to rapid quality deterioration and postharvest losses. This study evaluated the efficacy of a Zero‐Energy Cooling (ZEC) pot, an evaporative cooling technology, for preserving table egg quality in comparison to conventional refrigeration and ambient storage ...

Note: "Lock-in accelerometry" to follow sink dynamics in shaken granular matter [PDF]

, 2014
Understanding the penetration dynamics of intruders in granular beds is relevant not only for fundamental Physics, but also for geophysical processes and construction on sediments or granular soils in areas potentially affected by earthquakes.

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 ...
