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 ...

Cyclic loading triaxial testing of crushed rubble and lava

Bulletin of the International Association of Engineering Geology, 1984
This 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.

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.

A Review of Factors Affecting Cyclic Triaxial Tests

1978
The effects of testing procedures and material characteristics on the cyclic triaxial strength of cohesionless soils were reviewed with the intent of categorizing the significance of these factors for cognizance in future testing standards. It was found that specimen preparation methods, differences between intact and reconstituted specimens, density ...

Results of the cyclic triaxial testing on mechanically–biologically treated waste

Waste Management & Research: The Journal for a Sustainable Circular Economy
Accurate assessment of the dynamic strength characteristics of mechanically–biologically treated (MBT) waste is crucial for the construction and safe operation of landfill sites. Herein, samples of MBT waste from the Hangzhou Tianziling landfill were collected and subjected to consolidated undrained cyclic triaxial tests under four confinement levels ...

Regression Models for Validating Cyclic Triaxial Test Results

Geotechnical Testing Journal, 2011
Abstract 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

1988
Two 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.

Mechanical performance of recycled aggregates in cyclic triaxial testing

2017
In Belgium, more than 6,000 t of recycled concrete and masonry aggregates are produced every year, coming from civil engineering demolition works. They contain up to 50% of masonry. It is allowed to recycle them in road bases and subbases if they satisfy the requirements set in the standard specifications.

Cyclic Triaxial Tests at Low Stresses for Parameter Determination

1987
ABSTRACT The results of 2 drained cyclic triaxial tests at low isotropic stress are presented. For the tests to be meaningful the effective stress paths have been controlled from the very beginning and systematic errors as membrane penetration, bedding error and membrane restraint have been taken into account.
