Experimental Study of Failure Differences in Hard Rock Under True Triaxial Compression

Rock Mechanics and Rock Engineering, 2019
In 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, 2018
Abstract 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 .

Brittle-ductile transition and failure mechanism of Jinping marble under true triaxial compression

Engineering Geology, 2018
Abstract The research was focused on the execution of true triaxial compression tests and adopted acoustic emission (AE) and scanning electron microscopy (SEM). By doing so, the authors investigated the strength, deformation, AE, macroscopic and microscopic failure characteristics of Jinping marble in the 3-d stress space during brittle-ductile ...

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 ...
