Seismic behavior of electrical cabinets with cast-in-place anchors: influence of concrete cracks and multi-bay installation

open access: yesNuclear Engineering and Technology
Electrical cabinets are typically assembled in a multi-bay configuration, connecting two or more modules, and the structural implications of this setup must be carefully addressed. Concrete foundation cracks, often observed during field investigations at

Energy release and seismic flux

open access: yesAnnals of Geophysics, 2011
From the basic data and tlie previous results of priorpapers, we have made evaluations of the energy released and studied itsvariation. Its pulsative form is confirmed, which suggests several superposedperiods, perhaps of simple multiples of tlie undecenal of solar activity.For steps of a whole unity of m, the total approximated energy is computed.EN ...

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

open access: yesDeep 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.

A near-surface seismic scattered wave separation method

open access: yesPetroleum Exploration and Development, 2014
Considering that near-surface scattered waves could not be suppressed by conventional denoise method, this paper analyzes the characteristics of scattered waves and achieves the near-surface scattered wave separation by the seismic interferometry theory.

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

open access: yesDeep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.
