Evaluation of crushing stress at critical state of granulated coal ash in triaxial test

, 2014
A series of triaxial compression tests was performed on three types of granulated coal ash (GCA) to investigate their shear and crushing behaviour. The experimental results show that GCA displays different dilatancy characteristics to other natural ...

Study on Shear Strength of Unsaturated Red Clay with Triaxial Tests

Applied Mechanics and Materials, 2014
The subgrade of the most roads is easy to be of instability under the cyclic loading action of the vehicles with the soil unsaturated. The main idea of this paper is that researching the unsaturated red clay which is common in the subgrade building of Jiangxi province with the pressure plate test and triaxial shear test. And the main equipments are the

Modelling of cyclic behaviour of a cohesive soil by shear torsionaland triaxial tests

2004
This paper analyses the results of undrained cyclic torsional shear and compression loading triaxial tests run on undisturbed Noto soil. The cyclic torsional shear test was performed under stress control while the compression loading triaxial test was performed under strain control.

Elastic anisotropic viscoplastic modeling of the strain-rate-dependent stress-strain behavior of K0-consolidated natural marine clays in triaxial shear tests

, 2005
This paper presents a new three-dimensional (3D) anisotropic elastic viscoplastic (EVP) model for the time-dependent stress-strain behavior of Ko-consolidated marine clays.

The possibility of a statistical determination of characteristic shear parameters from triaxial tests

Beton- und Stahlbetonbau, 2018
AbstractThe shear strength of soils, commonly represented in terms of friction angle and cohesion, is an important input parameter for all geotechnical calculations. It can be assessed in the laboratory for example by triaxial tests. From the laboratory test results, the characteristic values for friction angle and cohesion have to be determined ...

Effect of Ambient Temperature Variation on Triaxial Shear Testing of Sands

Geotechnical Testing Journal, 2016
Abstract Triaxial shear tests are often carried out in a temperature controlled laboratory environment, and a few degrees change in ambient temperature are often neglected or considered to have negligible effect on the experiment.

A comparison of direct shear box tests with triaxial compression tests for a residual soil

Geotechnical and Geological Engineering, 1993
Residual soils are known to be bonded. The mechanical behaviour of undisturbed residual soils depends, therefore, not just on initial porosity and stress history but mainly on these bonds. This paper compares the stress-strain behaviour obtained from sets of drained triaxial compression tests and direct shear tests, both from undisturbed samples of ...
