摘　　要：地质灾害是河南省需重点应对的自然灾害类型,也是其交通运输正常安全运行要面对的重大挑战之一。该文针对地质灾害下河南省干线公路网韧性进行评估。首先,统计和解析了河南省地质灾害空间分布情况;其次,分析了河南省干线公路网建设发展现状和重要节点连通情况;然后,构建了地质灾害下的河南省干线公路网区域风险矩阵,并对每10 km干线公路所处廊道地质灾害点进行了量化测算;最后,得出地质灾害下河南省干线公路网韧性评估结果,并提出未来研究展望。Geological disaster is the type of natural disasters that Henan Province needs to focus on,as well as one of the major challenges to the normal and safe operation of its transportation.It was evaluated the resilience of trunk highway network in Henan Province under geological disasters.Firstly,the spatial distribution of geological disasters in Henan Province was analyzed,and then the current situation of the construction and development of the trunk highway network in Henan Province and the connectivity of important nodes were analyzed.Thirdly,the regional risk matrix of the trunk highway network in Henan Province under geological disasters was constructed,and the geological disaster points of the corridor where the trunk highway located every 10 kilometers were quantitatively calculated.Finally,the evaluation results of the toughness of the trunk highway network in Henan Province under geological disasters were obtained,and propose future research prospects.
