RES2021-14: Seismic Monitoring for Asset Management and Prioritization of Transportation Infrastructure

项目名称：	RES2021-14: Seismic Monitoring for Asset Management and Prioritization of Transportation Infrastructure
摘要：	While bridges in western Tennessee have been designed and/or retrofitted to withstand some seismic activity due to concerns for the New Madrid Fault, it is more challenging to make approaches resistant to impacts of liquefaction and seismic waves. Damages to bridge and/or overpass approaches could render bridges useless for evacuation and/or response activities. Therefore, employing low-cost sensing to monitor ground motion in the vicinity of bridges throughout the region could be valuable to inform decision making for response and asset management. Direct sensing and analytics could be utilized at bridges and in the surrounding areas (i.e., approaches and nearby slopes) with connections to existing communication networks to help identify and prioritize where significant ground movement has occurred that may require field response. Low-cost sensing can help offset the cost of labor and time for crews to physically visit and inspect bridges and approaches, especially along evacuation routes in the aftermath of an event. Review of frequency and severity of seismic waves can also provide insight to prioritize locations of other assets for health monitoring damage estimation following an event to improve public safety and return those assets to operational status.
