基于层次分析法的桥梁运营期安全风险评估

Assessment on Safety Risk of Bridge Operation Period Based on Analytic Hierarchy Process

摘要:

桥梁作为重要的交通基础设施，其安全性直接影响到交通运输的顺畅与公众的生命财产安全。随着使用年限的增加以及结构的逐渐老化，桥梁的安全性面临着越来越严峻的挑战。因此，科学有效地评估桥梁运营期的安全风险，及时发现潜在问题并采取适当的管理措施，显得尤为重要。为了实现这一目标，采用层次分析法对桥梁运营期安全风险进行综合评价，对主要的影响因素进行识别与分析。通过实际工程案例的分析研究，验证桥梁运营期风险评估体系及风险评估模型在实际工程应用中的适用性、科学性，从而为桥梁运营管理提供科学的决策依据。

Abstract:

As an important transportation infrastructure, the safety of bridges directly affects the smoothness of transportation and the safety of public life and property. With the increasing service life and the gradual aging of structures, the safety of bridges is facing increasingly severe challenges. Therefore, it is particularly important to scientifically and effectively assess the safety risks during the operation period of bridges, promptly identify the potential problems, and take the appropriate management measures. In order to achieve this goal, the analytic hierarchy process (AHP) is used to comprehensively evaluate the safety risks during the operation period of bridges, identify and analyze the main influencing factors. Through the analysis and research of actual engineering cases, the applicability and scientificity of the risk assessment system and risk assessment model during the bridge operation period in practical engineering applications are verified, providing scientific decision-making basis for bridge operation management.
