Forensic Assessment of a Bridge Downfall Using Bayesian Networks

Popis výsledku v původním jazyce

Bayesian networks proved to be a useful tool in many technical fields as well as in forensic sciences. The present paper proposes a novel application of Bayesian networks in forensic engineering, focusing on the analysis of technical causes of a catastrophic bridge downfall. During repair a road bridge over important railway lines suddenly slipped down from temporary supports. Incidentally at the same time an intercity train approached the location and crashed into the collapsed bridge at a high speed.Forensic investigation concerning causes of the bridge collapse was complicated due to the additional damage caused by the train. Moreover, the remaining structural elements of the collapsed bridge and temporary supports were shortly after the accident removed. Critical consideration of all possible causes supplemented by a Bayesian network finally resulted in identification of the most significant causes including insufficient foundation and overall stiffness of temporary supports.
