Case History Analysis of Bridge Failures due to Scour
Scour is a major cause for bridge failure. To understand the characteristics of bridge failures under scour conditions and provide useful information for scour countermeasure, this study reviewed and analyzed totally 36 historical cases of bridge failure due to scour, including their hydraulic, geotechnical, and structural conditions and failure modes. Based on the collected data, most of scour depths (i.e. up to 41%) ranged from 0.5 to 5 m; but, the maximum scour depth could be up to 15 m. Local scour was accounted for 64% bridge failures, followed by channel migration (14%), and contraction scour (5%). Possible bridge failure modes due to scour included vertical failure, lateral failure, torsional failure, and bridge deck failure. Approximately 70% of bridge failures were lateral and vertical. The findings from this study can be updated when more cases of bridge failure under scour conditions are collected and/or become available.
