The creep-seepage characteristics of rock under true triaxial compressions
Physics of FluidsCarbon storage, nuclear waste disposal, tunnels, and other underground engineering have a long service life and require accurate permeability control. The surrounding rock is subjected to a true triaxial stress state because of tectonic stress and engineering disturbance.

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.

Inelastic compaction and failure mode of Bleurswiller sandstone under true triaxial compression
2023Previous investigations of the compressive failure of porous rocks under true triaxial compression have focused on the brittle faulting regime. These studies have underscored the dependence of the peak stress state on the interplay of the three principal stresses.

Experimental Study of Failure Differences in Hard Rock Under True Triaxial Compression
Rock Mechanics and Rock Engineering, 2019In view of a previous study of the intermediate principal stress effect at a limited σ2 range, a series of true triaxial tests, covering a full range of intermediate principal stresses that vary from the generalized triaxial compression stress state (σ2 = σ3) to the generalized triaxial tensile stress state (σ1 = σ2), was carried out on sandstone and ...

Time-dependent behaviour and modeling of Jinping marble under true triaxial compression
International Journal of Rock Mechanics and Mining Sciences, 2018Abstract The time-dependent deformation, creep rate, and long-term strength of Jinping marble under different 3-D stress states were studied by using true triaxial creep experiment. A 3-D visco-elastic-plastic creep model, which can describe the accelerated creep， was developed according to the true triaxial time-dependent deformation curve .

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 ...

Brittle fracture in two crystalline rocks under true triaxial compressive stresses
Geological Society, London, Special Publications, 2005Abstract We employed our new polyaxial cell to carry out true triaxial compression tests on dry (jacketed) rectangular prisms of two crystalline rocks, in which different magnitudes of the least and intermediate principal stresses σ 3 and σ 2 were maintained constant, and the ...

Deformability properties of model granular soils under true triaxial compression conditions
Moscow University Geology Bulletin, 2013The study presents a review of modifications to the design of true triaxial test apparatuses and described a new mixed boundary apparatus to study the stress-strain behavior of coarse-grained soil under true triaxial compression conditions. It was shown that the deviatoric component plays an important role in affecting the volumetric compression of ...
