摘要

Monitoring bridge displacements under freight traffic can provide bridge managers with an objective indicator of safe and cost-effective operations. Excessive displacements that occur when trains cross a bridge can be used to compare bridge performance and to ensure safety of operations, whether to compare performance on the same bridge over time or compare bridge performance across a network of bridges. Railroad engineers want to quantify displacements that they can add to their regular inspections to inform maintenance, repair, and replacement operations.
