Behaviour of carbonated rocks under true triaxial compression
2011A true triaxial testing device has been developed in the nineties in the mining department of the Faculty of Engineering, Mons-Belgium. Since then data have been gathered from several rocks, among which various carbonated rocks exhibiting different mechanical behaviours.

True-triaxial compressive behaviour of concrete under passive confinement
Construction and Building Materials, 2017Abstract With the new triaxial testing system developed to generate passive confinement, 117 normal-weight concrete cubes were tested under 13 loading schemes, including biaxial compression and triaxial compression with both uniform and non-uniform passive confinement.

Strength and deformation characteristics of jointed media in true triaxial compression
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1978Abstract Laboratory triaxial compression tests to investigate the strength and deformation characteristics of jointed rocks under truly triaxial states of stress (σ 1 ≠ σ 2 ≠ σ 3 ) were conducted on an idealized model of a jointed rock in a specially designed loading arrangement.

Damage Evolution and Failure Behavior of Sandstone under True Triaxial Compression
Geotechnical Testing Journal, 2018Abstract In the present study, a series of conventional triaxial tests (CTTs) and true triaxial tests (TTTs) were performed on sandstone through a self-developed true triaxial testing system, which was combined with acoustic emission (AE) monitoring and X-ray computed tomography (CT) scanning technique to systematically study the damage ...

Strength and deformability of a low-porosity sandstone under true triaxial compression conditions
International Journal of Rock Mechanics and Mining Sciences, 2020Abstract True triaxial tests ( σ 1 ≥ σ 2 ≥ σ 3 ) were conducted on the Zigong sandstone with a relatively low porosity of ~6.5% with the aim of assessing the influence of the intermediate principal stress σ 2 on the strength and deformability. Three series of true triaxial tests ( σ 3 = 0, 20,

True triaxial cyclic behavior of concrete and rock in compression
International Journal of Plasticity, 1987Abstract Results from true triaxial cyclic tests on concrete are presented and compared with corresponding ones for dense rocks (mainly marbles) obtained under the same laboratory conditions. Common basic characteristics are confirmed regarding the essential effect of intermediate stress, the cataclastic mode of deformation under low confinement, the

Volumetric Properties of Concrete under True Triaxial Dynamic Compressive Loadings
Journal of Materials in Civil Engineering, 2019AbstractAlmost all of the available test data for pressure–volumetric strain curves [equations of state (EoS)] of concrete are based on static triaxial tests and one-dimensional impact tests, for e...

Deformability characteristics of a rock mass under true-triaxial stress compression
Geotechnical and Geological Engineering, 2006In this paper an experimental study was planned on rock mass model with three joint sets under triaxial and true-triaxial stress states to assess the influence of joint geometry and stress ratios on deformational behaviour of rock mass. The physical models were composed of three continuous orthogonal joint sets in which joint set-I was inclined at ...

Strength and failure characteristics of jointed marble under true triaxial compression
Bulletin of Engineering Geology and the Environment, 2019The rock structure and three-dimensional stress state play a vital role in the mechanical behaviour of rock masses. Here, a series of true triaxial compression tests (σ1 > σ2 > σ3) are conducted on jointed marble (50 × 50 × 100 mm3) containing a natural stiff joint, taken from the China Jinping Underground Laboratory (CJPL-II) project.

Compression and Shear Strength Characteristics of Unsaturated Intact Loess in True Triaxial Tests
Geotechnical Testing Journal, 2020ABSTRACT Previous studies of shear behavior from suction-controlled direct shear tests or triaxial tests focused mainly on remolded soils. Limited attention has been paid to suction measuring on unsaturated intact soil. In this paper, two series of saturated drained tests and unsaturated constant water content (CW) tests containing ...
