为全面评估都市圈道路网络韧性，基于加权复杂网络理论和韧性理论，构建了都市圈路网拓扑韧性评估模型。通过考虑路段完全中断和容量退化，从结构和功能两个维度对道路网络韧性进行系统分析，并以成都都市圈道路交通网络为例进行验证分析。研究结果表明，网络韧性曲线受攻击策略的影响对连边介数下的攻击表现出最高的脆弱性；基于韧性值减少量的连边重要度与连边的拓扑重要性指标显著相关；功能韧性受系统功能恢复能力制约，对容量的变化较为敏感；不同恢复策略优先级下的韧性值存在差异，路段流量优先的恢复策略最优。研究可为都市圈道路网络的韧性评估与优化提供理论依据和实践指导。
Abstract：The transportation system is vulnerable to regional disasters, and a comprehensive assessment of network resilience is essential to maintain the smooth operation of the road network.Based on the complex network theory, a topology model of metropolitan road network is constructed.A resilience evaluation model is proposed, which considers the complete failure and capacity degradation of the road network, and reveals the resilience characteristics of the road network from two aspects of structure and function.The road traffic network of Chengdu metropolitan area is selected for verification and analysis.The results show that the network is more resilient to intentional attacks based on edge weights, and more vulnerable to intentional attacks based on edge betweenness.The degree centrality and betweenness centrality of connected edges are related to the importance of connected edges.The functional resilience is limited by the functional recovery of the system and is greatly affected by the flow.There are differences in the repair effect under different recovery strategy priorities, and the recovery strategy with priority of road traffic is the best.
