Mohr-Coulomb Failure Condition and the Direct Shear Test Revisited
Acta Polytechnica, 2004 An alternative critical plane orientation is proposed in the Mohr-Coulomb failure criterion for soils with an extreme property. Parameter identification from the direct shear test is extended to incude the lateral normal stress.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas
Deep Underground Science and Engineering, EarlyView.This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Deep Underground Science and Engineering, EarlyView.This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Journal of Rock Mechanics and Geotechnical EngineeringHydraulic fracturing then fluid circulation in enhanced geothermal system (EGS) reservoirs have been shown to induce seismicity remote from the stimulation – potentially generated by the distal projection of thermoporoelastic stresses.

Deep Underground Science and Engineering, EarlyView.To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Earth and Planetary PhysicsTwo long-term slow slip events (SSEs) in Lower Cook Inlet, Alaska, were identified by Li SS et al. (2016). The earlier SSE lasted at least 9 years with Mw ~7.8 and had an average slip rate of ~82 mm/year.

Deep Underground Science and Engineering, EarlyView.This study derives an explicit expression for the lining force transmission coefficient of underground gas storage lined rock caverns (LRCs) via the complex variable function method, considering the displacement release coefficient. Taking the 1‰ tensile strain of surrounding rock as the criterion to determine lining thickness, it systematically ...

Geophysical Research LettersRecent megathrust earthquakes preceded by slow slip events highlight static stress transfer as a key triggering mechanism. However, there are limited insights into the interplay between static stress transfer and elevated fluid pressure before earthquake

Deep Underground Science and Engineering, EarlyView.This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.
