改进层次分析法在桥梁运营风险评估中的应用

Application of IAHP in Risk Assessment of Bridge Operation

摘要: 为了确保桥梁工程的安全性和可靠性，对桥梁运营风险进行评估则显得尤为必要。针对桥梁工程运营阶段的风险管理问题，本文提出了运用改进层次分析法进行评估的方法。在传统层次分析法的基础上，采用标度扩展法构造判断矩阵，利用指标间的传递性，避免了传统方法判断矩阵的一致性检验，简化了计算。该方法能够较好地从各级风险指标中判别主要因素，有利于桥梁运营阶段风险评估指标的量化，可为桥梁管理者和养护者提供科学合理的参考依据，以提高桥梁工程的运营风险管理水平。

Abstract: To ensure the safety and reliability of bridge engineering, it is necessary to evaluate the operational risks of bridge engineering. This article proposes a method for evaluating operational risks of bridge engineering using the Improved Analytic Hierarchy Process (IAHP). Based on the traditional AHP, the scaling method is used to construct the judgment matrix, and the transitivity between indicators is used to avoid consistency testing of the traditional method, simplifying the calculation. This method can effectively identify the main factors from various levels of risk indicators, facilitating the quantification of risk assessment indicators during the operational phase of bridge engineering. It can provide scientific and reasonable reference for bridge managers and maintainers, and improve the operational risk management level of bridge engineering.
