Centrifugal model tests of the Lodalen landslide

Canadian Geotechnical Journal, 1978
The slide which occurred at Lodalen, Oslo in 1954 was used to compare the behaviour of soil models tested in a centrifuge with a well-documented prototype event.The paper describes the centrifugal testing of three models prepared from block samples in which an attempt was made to simulate the stress history of the site.

Centrifuge model testing at Caltech

International Journal of Soil Dynamics and Earthquake Engineering, 1983
Abstract In the past eight years a variety of model tests has been performed on the geotechnical centrifuge at Caltech. They include soil mechanics experiments, such as static and dynamic pile and foundation tests, and other investigations of a more geographical nature where ground faulting and earthquake motions have been modeled.

Numerical modelling of centrifuge tests on tunnel–soil systems

Bulletin of Earthquake Engineering, 2014
The number of tunnels in seismic regions has grown significantly in recent decades. It has usually been assumed that tunnels perform better than surface structures during seismic events. However, recent cases have shown that tunnels can be significantly damaged by seismic events.

Centrifugal model tests on face failure of earth pressure balance shield induced by steady state seepage in saturated sandy silt ground

Tunnelling and Underground Space Technology, 2018
When tunnelling in a stratum with a high level of water (e.g., tunnelling below the river) by earth pressure balance shield, seepage due to the difference of hydraulic head between the ground and the shield’s chamber can result in the failure of tunnel ...

Centrifuge modelling of plate bearing tests

2012
Current guidance given on plate bearing testing of granular soils suggests that the plate be at least five times the nominal size of the coarsest material. However this limiting ratio can have a huge influence on the reaction load required from plant and resources when conducted to confirm strength parameters used in the design of the sub grade and ...

Model tests of silo discharge in a geotechnical centrifuge

Powder Technology, 2016
Abstract Scaled models are often used to study the behaviour of silo discharge, however the effects of gravity on silo discharge have not yet been quantified. In this paper, the effects of gravity on silo discharge and internal flow patterns are investigated with reference to the widely used Beverloo correlation.

PHOTOGRAMMETRY IN CENTRIFUGAL TESTING OF SOIL MODELS

The Photogrammetric Record, 1973
AbstractSince 1969 photogrammetric techniques have been employed as a means of obtaining precise measurements of surface movement of soil models spinning in a centrifuge at a speed of up to 45 m s‐1. Over 100 soil model tests have been performed on about 12 different types of soil stability problem during this period.

Centrifuge model tests on backfill stability

Canadian Geotechnical Journal, 1986
The 6 m diameter, 30 g-tonne geotechnical centrifuge at Queen's University is described. Results from eight model tests, carried out on plain cemented sand samples representing mine backfills, are presented. These data show that the stable prototype backfill heights obtained from centrifuge tests exceed the failure heights predicted from unconfined ...

Centrifuge Model Tests on Bearing Capacity of Clay

Journal of Geotechnical Engineering, 1984
A series of centrifugal model tests to investigate the bearing capacity of a strip footing on normally consolidated Kawasaki clay was performed. The proposed prototype is a normally consolidated clay foundation having undrained shear strength increasing with depth.

CENTRIFUGE TESTING OF MODEL MASONRY ARCH BRIDGES.

Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 1998
The effect of gravity is fundamental in the behaviour of masonry arch bridges, but previous laboratory testing of scale model arches has ignored its effect. A series of centrifuge tests on scale models constructed using real masonry materials is described - the first model arch bridges to be tested in a correctly scaled gravity field. The test geometry
