Liquefaction Study of Heterogeneous Sand: Centrifuge
Geotechnical Testing Journal, 2011 From past numerical research and small scale laboratory tests, it has been observed that more excess pore water pressure (EPWP) is generated during earthquakes in a heterogeneous sand deposit than in the corresponding homogeneous sand with relative density equal to the average relative density of the heterogeneous sand.

Triaxial compression tests on a crushable sand in dry and wet conditions [PDF]
, 2015 A calcareous sand from the Persian Gulf is subjected to a series of dry and fully drained saturated triaxial shear tests. The samples are prepared at relative densities of 65% and either left dry or saturated. They are consolidated to confining pressures

Liquefaction resistance of partially saturated sands
, 2022 Abstract Partially saturated sands with occluded gas bubbles may occur naturally in the field or can be created artificially as a way of mitigating liquefaction effects. The gas bubbles in pore spaces significantly alter the bulk modulus of pore fluid and consequently affect the excess pore pressure generation and liquefaction behavior of sands.

Flow Potential of Sand During Liquefaction
Soils and Foundations, 1998 In order to quantify the tendency to flow characteristics of sandy soils, the maximum value of excess pore water pressure ratio developed during undrained monotonic loading test was taken as an index property and defined as flow potential. Triaxial compression tests, triaxial extension tests and simple shear tests on Toyoura sand were conducted by ...
