Dynamic centrifuge model tests on clay embankments

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989
Centrifuge modelling is a valuable means for obtaining data to study the response of geotech-nical structures to infrequent or extreme events such as earthquakes. The results of a study of five clay embankments subjected to 23 simulated earthquakes on the Cambridge geotechnical centrifuge are presented and analysed.

Bayesian Model Calibration Using Geotechnical Centrifuge Tests

Journal of Geotechnical and Geoenvironmental Engineering, 2009
The predicted performance using a geotechnical prediction model is expected to deviate from reality. A practical approach to assess the model error is through calibration with observed performances in physical model tests. In this paper, a Bayesian framework of model calibration using centrifuge modeling tests is proposed and the procedure of model ...

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.

Miniature Centrifuge Modeling for Conventional Consolidation Test

Geotechnical Testing Journal, 2018
Abstract Consolidation parameters are usually determined in the laboratory with oedometer tests in earth gravity conditions (1 g). However, performing the test is very time-consuming. Although dynamic approaches in which higher accelerations are applied have been developed as an alternative to the static approaches to reduce the duration

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 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.

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 ...

Centrifugal Model Tests on Vertical Anchor Plates

Journal of Geotechnical Engineering, 1983
The stress displacement behavior of vertical anchor plates and continuous anchor walls in dense sand when subjected to horizontal pull‐out forces is presented. Results of a large number of centrifugal tests on 1 in. (25 mm) and 2 in. (50 mm) models subjected to accelerations of up to 40 gravities are presented and the effects of anchor geometry 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 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 ...
