Abstract

Roads often suffer significant damage following an earthquake, which can be attributed to various factors. This study aims to identify and quantify these factors and provide an estimation of the vulnerability index for the studied road section. The vulnerability index enables the classification of a section based on its vulnerability. To achieve this, we propose an estimation method for the seismic vulnerability index of a road, which uses the Analytic Hierarchy Process (AHP) to determine the weights of the identified parameters. The resulting vulnerability index value facilitates the classification of the road section using the proposed scale. Additionally, we present several case studies that validate the obtained results, aligning with seismic feedback. Moreover, a seismic scenario was simulated on an urban network using a geographic information system (GIS) to predict the seismic behavior of the road network in the target city. Keywords: Vulnerability, Road Damages, Analytic Hierarchy Process, Seismic Vulnerability Index, Earthquake DOI： https://doi.org/10.35741/issn.0258-2724.58.5.39

地震情况下道路易损性评估

地震发生后，道路经常受到严重破坏，这可归因于各种因素。本研究旨在对这些影响因素进行识别和量化，并对研究路段的脆弱性指数进行估算。通过脆弱性指数，可以根据一个区段的脆弱性对其进行分类。为此，提出了一种道路地震易损性指标的估计方法，该方法采用层次分析法确定识别参数的权重。得到的脆弱性指数值便于使用建议的尺度对路段进行分类。此外，我们提出了几个案例研究来验证所获得的结果，与地震反馈一致。此外，利用地理信息系统(GIS)在城市网络上模拟地震场景，预测目标城市道路网络的地震行为。关键词:易损性，道路损害，层次分析法，地震易损性指数，地震DOI: https://doi.org/10.35741/issn.0258-2724.58.5.39
