Safety Risk Assessment for Continuous Rigid Frame Bridge with High Pier in Mountain Area

Based on the analysis of theoretical framework of bridge risk assessment,the key technologies of safety risk assessment for continuous rigid frame bridge were studied combined with the practical bridge risk assessment. The risk identification and risk estimation methods were optimized. The fast risk source identification method was applied to identify risks,and the optimal Delphi method was applied to analyze risk probability level and risk loss level in the bridge whole life cycle. Through the research on the safety risk assessment for continuous rigid frame bridge, more efficient methods are provided.
