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.

Modelling of Fatigue-Type Seismic Damage for Nuclear Power Plants

Open Journal of Safety Science and Technology, 2011
Abstract Assessment of the safety of the nuclear power plants and evaluation of the plant condition after an earthquake require the knowledge of the fragility of structures and components. In the paper options for improvement of existing methods of the modelling of plant fragilities are outlined based on the interval and p-box theories, use of ...
