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 ...

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 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

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 Model Tests of Rainfall-Induced Landslides

2015
Rainfall-induced landslides and debris flows constitute very serious threats to human lives and infrastructure. In many cases, rainfall characteristics which cause the initiation of landslides are not very well determined and this might lead to the misunderstanding of the failure mechanism, the kinematic characteristics and the run-out distance of the ...

Simulation of Climatic Conditions in Centrifuge Model Tests

Geotechnical Testing Journal, 1991
Abstract A review is presented of the need for simulation of effects associated with tide, rainfall, temperature variations, etc., in geotechnical centrifuge models. Interest in the overall theme was generated by a perceived need to model rainfall in long-term testing of models of an embankment which was otherwise found to dry out.

Numerical Simulation and Analyze for Centrifuge Model Tests

2007
RFPA-Centrifuge is a Finite Element Method analyse system which is founded on fundamental principle of centrifuge model test and edited by our research center. Author used this system to simulate the centrifuge model tests about a tunnel. The numerical simulation results are greatly similar to the experimental test results.

Centrifuge Model Test of Vacuum Surcharge Preloading

CICTP 2015, 2015
Vacuum surcharge preloading for stabilizing soft soil foundation is becoming an increasingly popular ground improvement technique. Although many studies have been reported in literatures, few articles adopted the centrifuge model test. The Centrifuge model test technique is adopted to simulate a gravity field by changing centrifugal acceleration, in ...

Simulation of Ground Loss in Centrifuge Model Tests

Geotechnical Testing Journal, 1993
Abstract This note presents a computer-controlled mechanical system developed to simulate ground loss in centrifuge model tests. The main application of the system to date had been in the field of mining subsidence prediction. This involves the replication of total extraction of thin mineral seams at depth.

Cyclic Static Model Pile Tests in a Centrifuge

Offshore Technology Conference, 1979
ABSTRACT Scaling relations for soil studies indicate that certain model behaviors will represent correctly those of the prototype if the model is subjected to an acceleration proportional to the model scale. The most convenient way of accomplishing this is to perform model tests in a large centrifuge. Lateral cyclic
