暴雨灾害下城市轨道交通车站韧性关键影响因素研究

Key Influencing Factors of Urban Rail Transit Station Resilience under Rainstorm Disaster

研究暴雨灾害对车站韧性的关键影响因素,对保证居民的安全出行有重要意义。首先从韧性3属性(抵抗力、恢复力、适应力)中选出20个车站韧性影响因素,然后以影响因素间的邻接关系为研究数据,运用社会网络分析法(SNA)中凝聚子群分析的CONCOR法分析因素网络中次级团体结构的相互关系,最后运用SNA的中心度分析来筛选出车站韧性的关键影响因素。研究结果可以看出,暴雨灾害下车站韧性的关键影响因素为:防汛监控能力、防汛挡水能力、人员疏散效率、防汛排水能力、防汛资金投入、人员协调配合能力、防汛应急预案制度和防汛培训演练。

It is of great significance to study the key influencing factors of rainstorm disaster on station resilience to ensure the safe travel of residents.Firstly,20 factors affecting station resilience were selected from the three attributes of resilience(resistance,resilience,and adaptability).Then,taking the adjacency relationship between influencing factors as the research data,the CONCOR method of cohesive subgroup analysis in social network analysis(SNA)was used to analyze the relationship of secondary group structure in factor network.Finally,the centrality analysis of SNA was used to screen out the key influencing factors of station resilience.The research results show that the key influencing factors of station resilience under rainstorm disaster are:flood control monitoring capability,flood control water retaining capability,personnel evacuation efficiency,flood control drainage capability,flood control fund investment,personnel coordination and cooperation capability,flood control emergency plan system and flood control training drill.
