【摘要】 2022年9月5日12时57分，四川省泸定县发生6.8级地震。受自然地理环境等因素的影响，本次地震对灾区公路交通网络造成了比较严重的破坏，给震后应急救援工作带来了较大阻碍，极大地考验了灾区交通网络的应急服务能力。本文介绍了灾区交通网络的概况及其地震破坏情况，建立了路网应急服务能力评价方法，并将单位时间到达重点救援目标的最大交通量作为其评价指标。以本次地震灾区的交通网络为例，结合交通网络应急抢通过程的考察数据，对交通网络应急服务能力的下降及其恢复过程进行了分析，对灾区交通网络地震韧性进行了定性讨论，以期为交通网络的地震韧性评价提供参考。更多还原

【Abstract】 At 12:57 on September 5,2022,an Ms6.8 earthquake occurred in Luding County,Sichuan Province. Affected by factors such as the natural geographical environment etc.,the earthquake caused serious damage to the highway transportation network in the disaster area,which brought great obstacles to the emergency rescue work after the earthquake. The post-earthquake rescue process severely tested the emergency service ability of the transportation network in the disaster area. The general situation and the seismic damage of the highway transportation network were first introduced in this paper,then an evaluation method for transportation network emergency service capability based on the maximum traffic volume arriving at key rescue targets per unit time was proposed. Taking the transportation network in the disaster area as an example,combined with the investigation data of the emergency repair process of the transportation network,this paper analyzed the decline and recovery process of the emergency service ability of the transportation network,and qualitatively discussed the seismic resilience of the transportation network. It is expected that the work in this paper can provide some valuable references to the seismic resilience evaluation of transportation networks.更多还原
