摘要
在分析桥梁安全风险评估理论框架的基础上,结合实际桥梁安全风险评估,对连续刚构桥安全风险评估的关键技术进行研究,优化了风险辨识和风险估测方法。对桥梁全寿命周期应用快速风险源辨识法进行风险辨识,应用优化德尔菲法确定风险概率等级和损失等级。通过本次连续刚构桥安全风险评估研究,为类似桥梁工程安全风险评估提供了更加高效的方法。
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.
