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.

Dynamic compression behaviors of concrete under true triaxial confinement: An experimental technique
Mechanics of Materials, 2020Abstract A dynamic testing system for concrete-like material under static triaxial confinements is developed in the present article. The cubic specimen with length 50 mm is constrained by six steel square bars. The static triaxial confinements are applied on the specimen through six steel bars that independently servo-controlled by three hydraulic ...

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 ...

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 .

Hydraulic Stimulation Experiments in a Decimeter-scale True Triaxial Compressive Apparatus
Geothermal energy is considered a sustainable energy source for the transition to a carbon-neutral economy. In Central Europe, sufficiently hot source rocks are buried deep underground and comprise tight crystalline basement formations. To extract their thermal energy, hydraulic stimulation is used to create efficient heat exchangers in the context of ...Julian Osten +8 more
