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.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Numerical research on anti‐dislocation measures design of deep‐buried tunnels in an anisotropic rock mass area

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 ...
