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

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

Deep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Evolution of the overlying strata structure and characteristics of ground pressure behavior under the influence of tectonic stress

Frontiers in Earth Science
The evolution of overlying strata structures significantly influences the manifestation of ground pressure behavior in working faces. The mechanism through which tectonic stress influences the evolution of overlying rock structures remains unclear.

Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

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.

Seismicity of the Noto Peninsula: Spatial Patterns, Shallow Seismic Zones, and Possible Volcano-Related Signals

Trends in Ecological and Indoor Environmental Engineering
Background: Japan's complex tectonic setting produces intense seismicity, yet reliable earthquake prediction remains unresolved. Recent data-driven approaches suggest that classical models may be insufficient, highlighting the value of exploratory ...

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

Numerical simulation study on the evolution of the temperature field and frozen wall in fractured rock mass

Deep Underground Science and Engineering, EarlyView.
The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in
