Seismic performance of underground facilities
A workshop was held in Augusta, GA, February 11-13, 1981 to review and assess the state-of-the-art for determining and predicting earthquake damage to underground facilities. The papers presented related to data collection and analysis, modeling, and repository design. Discussion groups addressed seismology, rock mechanics and hydrology, modeling, design, and licensing, siting, and tectonics. Most scientists in attendance believed that enough was known to proceed with site selection, design, and licensing of a waste repository. However, there was recognition of several items of research that would enhance understanding of the subsurface effects of seismicity. In general, the subsurface effects of earthquakes are substantially less than their surface effects. This conclusion is supported by both observation and by modeling studies. The absence of wave reflections, the absence of high flexural stresses, and the absence of poor soil conditions contribute to the improved seismic performance of subsurface facilities. Seismic considerations for geologic disposal of nuclear waste vary with the phase of operation. During construction and waste loading, the primary concern is for the safety of onsite personnel. However, during long-term waste storage, the principal interest is in the migration of contaminants due to seismic cracking and enhancement of permeability. Backfilling the storage facility will mitigate this effect.
