Static and Cyclic Triaxial Testing of Ballast and Subballast
Journal of Geotechnical and Geoenvironmental Engineering, 2005This 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 ...

A Compilation of Cyclic Triaxial Liquefaction Test Data
Geotechnical Testing Journal, 1979Abstract 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 ...

Cyclic triaxial tests with continuous measurement of dissipated energy
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1983Abstract This article describes conventional cyclic triaxial tests on a uniform sand in which the amount of energy dissipated by the specimen was continuously monitored. Energy monitoring was achieved by means of a digital circuit that automatically integrated the force-displacement signals as the test progressed.

Cyclic loading triaxial testing of crushed rubble and lava
Bulletin of the International Association of Engineering Geology, 1984This paper describes a laboratory investigation into the suitability of crushed rubble as a substitute for conventional road base materials. The rubble investigated was a mixture of crushed concrete and crushed bricks, whilst lava from the Eifel was chosen as a reference material.

The stable state in cyclic triaxial testing on sand
Soil Dynamics and Earthquake Engineering, 1994Abstract 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.

Regression Models for Validating Cyclic Triaxial Test Results
Geotechnical Testing Journal, 2011Abstract Cyclic triaxial tests are commonly used to evaluate a soil’s potential for liquefaction during seismic events. Following testing, it is necessary to evaluate the validity of the test results. This can be a difficult task unless the engineer has previously acquired a reasonable amount of experience with this type of testing.

Cyclic Triaxial Strain-Controlled Testing of Liquefiable Sands
1988Two series of undrained cyclic triaxial strain-controlled tests were performed on two different Imperial Valley, California, silty sands which liquefied during an earthquake in 1981. Both intact and reconstituted specimens were tested, and the testing procedures are described.

Unloading Elastic Behavior of Sand in Cyclic Triaxial Tests
Geotechnical Testing Journal, 2016Abstract 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.

Cyclic and Postcyclic Triaxial Testing of Ballast and Subballast
Journal of Materials in Civil Engineering, 2016AbstractBallast 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

The specific deviatoric energy to liquefaction in saturated cyclic triaxial tests
Proc. of the 7th International Conference on Earthquake Geotechnical Engineering, 2019Within the European project LIQUEFACT, cyclic triaxial tests were carried out on an Italian sand, Pieve di Cento sand, taken from a field trial located in Emilia Romagna (Ita-ly), which was affected by liquefaction during the 2012 earthquake. The cyclic resistance curve of that sand was obtained in laboratory on reconstituted specimens with a low ...
