Static and Cyclic Triaxial Testing of Ballast and Subballast

Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2005
This paper discusses the triaxial testing of a ballast material and a subballast material, which are noncohesive, granular materials pically used for construction of a railway track substructure. Both static and cyclic triaxial tests were conducted. The cyclic triaxial tests simulated the behavior of these railway substructure materials under a large ...

Cyclic Triaxial Tests on Remoulded Clays

Journal of Geotechcnical Engineering, 1984
Data are presented from cyclic triaxial tests on remoulded clays with load or displacement control. The ability of simple load control tests to predict strains developed in complex (storm profile) tests is found inadequate. It is suggested that only the minimum cyclic stress ratio associated with the fully weakened state has any direct design relevance.

Cyclic Triaxial Tests on Frozen Sand

Engineering Geology, 1979
ABSTRACT Li, J.C., Baladi, G.Y. and Andersland, O.B., 1979. Cyclic triaxial tests on frozen sand. Eng. Geol., 13: 233–246. Strain-controlled cyclic triaxial tests were performed on a one-size silica (Ottawa) sand artificially frozen into 71.1-mm-diameter cylindrical samples.

Cyclic triaxial strength of standard test sand

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1976
A cooperative cyclic triaxial strength test program was performed by eight university, government, and consulting laboratories to define the cyclic strength characteristics often called the liquefaction potential or cyclic mobility of a standard test sand.

Triaxial tension–compression tests for multiaxial cyclic plasticity

International Journal of Plasticity, 1999
Abstract The aim of this paper is to present triaxial tension–compression tests and a new triaxial specimen devoted to the study of cyclic plasticity under non-proportional loadings. Because the stress state in the central part of the specimen is not homogeneous, the analysis of the tests need a 3D finite element computation.

A Compilation of Cyclic Triaxial Liquefaction Test Data

Geotechnical Testing Journal, 1979
Abstract A data base on cyclical soil strength would be of significant assistance in many phases of site evaluation where detailed complete cyclical soil testing is not available or could not economically be obtained. The objective of this study was to develop a partial data base for determining the seismic strength of saturated ...

The stable state in cyclic triaxial testing on sand

Soil Dynamics and Earthquake Engineering, 1994
Abstract The paper will describe a number of new characteristic phenomena of sand under cyclic loading, which have been discovered by triaxial cell testing, at the Soil Mechanics Laboratory at Aalborg University using test specimens with equal height and diameter.

Cyclic and Postcyclic Triaxial Testing of Ballast and Subballast

Journal of Materials in Civil Engineering, 2016
AbstractBallast and subballast are two layers of noncohesive, granular materials with different grain sizes filled in the track substructure to bear traffic loadings from train passages. The performance and sustainability of a track substructure depend on both of these two granular layers. This paper presents the experimental results of cyclic triaxial

Unloading Elastic Behavior of Sand in Cyclic Triaxial Tests

Geotechnical Testing Journal, 2016
Abstract In this paper, digital image technology was used in the surface-deformation measurement of soil, making it possible to monitor the axial, radial, and volumetric deformations and the deformation distribution over the entire surface of specimens in triaxial tests.

Defining Y2 Yielding From Cyclic Triaxial Tests

Geotechnical Testing Journal, 2013
Abstract This paper presents the yielding characteristics of overconsolidated Bootlegger Cove Formation (BCF) clays extracted from the Port of Anchorage construction site. Additionally, it extends the critical shear strain concept to define the point at which irrecoverable deformations begin (Y2 yielding) to the case of fully reversed ...
