Abstract

Influence on the safety of bridge structure, train and vehicle travelling stemming from the immediate vicinity of adjacent and parallel high-speed railway bridges and highway is not yet clarified, and pertinent analysis and assessment is not yet reported. In this paper, risk factors due to the closely arranged high-speed railway bridge and highway are discerned and general framework of assessment process is established considering the interactive characteristics of adjacent high-speed railway bridge and highway. Effects and consequences of each risk factor, including collision, explosion and fire resulting from vehicles, airflow, glare and noise resulting from high-speed trains, are investigated by means of theoretical analysis, numerical simulation and field measurement through a case study. Risk evaluations of each risk factor are conducted in terms of risk matrix established in this paper considering probability of occurrence and consequence comprehensively. Accordingly, a variety of validated risk mitigation measures are presented.
