Deep Underground Science and Engineering, EarlyView.This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Fluvial and tectonic geomorphology of orogenic plateaux [PDF]
, 2013 Geomorphology is an expression of processes acting upon an area. The links between driving processes and the resulting geomorphology are far from being fully understood.

Controlling effect of palaeo-tectonic stress field on gas occurrence [PDF]
The paleo-tectonic stress field was hereby inverted by using the stereographic projection method through field and underground observations of conjugate shear joints.

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Deep Underground Science and Engineering, EarlyView.A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such

Upper plate tectonic stress state may influence interseismic coupling on subduction megathrusts
, 2012 We document a correlation between along-strike variation in interseismic coupling depth on subduction interfaces, and the upper plate tectonic stress state in New Zealand, Vanuatu, and southwest Japan.

Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Minimum stress and pore fluid pressure in sedimentary basins [PDF]
, 2001 Leak-off pressures (LOPs) recorded during leak-off tests (LOTs) conducted down boreholes are often used to estimate the magnitude of the minimum stress (usually assumed to be horizontal – S(_h)) in the subsurface.

Anisotropic scaling of tectonic stylolites: A fossilized signature of the stress field? [PDF]
, 2010 Vertical stylolites are pressure solution features, which are considered to be caused by horizontal tectonic loading, with the largest principal compressive stress being (sub-)parallel to the Earth's surface. In the present study we analyze the roughness
