摘要：为评估暴雨内涝对城市道路交通系统的安全韧性影响,通过分析道路交通系统安全韧性因素,划分排水网、道路网、交通网及应急网等4层网络,构建城市道路交通系统韧性网络分层模型,并给出模型内涵与机制;结合该分层模型设计系统韧性评估指标体系,采用模糊层次分析法(FAHP)给出定性和定量相结合的系统韧性评估方法;最后,以北京某区域暴雨内涝灾害实例进行验证分析。结果表明:3次降雨后,系统韧性机能曲线均产生严重下降,降幅分别为68.18%,51.28%和59.52%,系统平均韧性为0.57,韧性评估结果为0.53,评估结果和实例分析基本一致。所提方法能够开展暴雨内涝下的城市道路交通系统安全韧性及演化趋势分析,准确评估系统安全韧性,从而提高系统安全韧性的管理水平。
In order to evaluate the impact of a rainstorm waterlogging on the resilience of urban road traffic systems,the resilience network hierarchical model of the urban road traffic system was constructed by analyzing the safety resilience factors of the road traffic system.Four layers of networks were divided,including drainage network,road network,traffic network and emergency network,and the connotation and mechanism of the model were given.Combined with the hierarchical model,a resilience evaluation index system was designed.Furthermore,a qualitative and quantitative evaluation method of urban road traffic system resilience was given by using FAHP.Finally,a case study of a rainstorm waterlogging disaster in a region of Beijing was carried out.The results show that the resilience function curves of the system all decreased seriously after three rainfalls,with the decline ranges of 68.18%,51.28%and 59.52%,respectively.The average resilience of the system is 0.57,and the resilience evaluation result is 0.53.The evaluation result is consistent with the example analysis.The proposed method can analyze the safety resilience,and evolution trend of urban road traffic systems under rainstorm waterlogging,realize the accurate evaluation of system safety resilience,and improve the management level of system safety resilience.
