Journal ArticleDOI
Soil deformation measurement using particle image velocimetry (PIV) and photogrammetry
TL;DR: A deformation measurement system based on particle image velocimetry (PIV) and close-range photogrammetry has been developed for use in geotechnical testing as mentioned in this paper.
Journal ArticleDOI
Improved image-based deformation measurement for geotechnical applications
TL;DR: The updated approach combines a range of advances in image analysis algorithms and techniques best suited to geotechnical applications and achieves an improvement by at least a factor of 10 in measurement precision relative to the most commonly used particle image velocimetry (PIV) approach.
Journal ArticleDOI
Evaluation of landslide triggering mechanisms in model fill slopes
TL;DR: In this article, the authors evaluate two candidate triggering mechanisms (static liquefaction and the transition from slide to flow due to localised transient pore water pressures) against observations of slope behaviour obtained from highly instrumented centrifuge model tests.

Earth pressures on unyielding retaining walls of narrow backfill width
W.A. Take,A J Valsangkar +1 more
TL;DR: In this paper, an extensive series of centrifuge tests has been performed to evaluate the use of flexible subminiature pressure cells in the centrifuge environment and their subsequent use to measure lateral earth pressures behind retaining walls of narrow backfill width.
