摘　　要：为了降低路网抗灾成本并保障路网快速连通,研究道路交通网络多阶段灾害应对能力优化的问题.建立综合灾前应急工作站点选址和灾后路网恢复决策的3层规划模型,其中特别考虑了应急救援设施和后勤保障资源在耗尽性、运输方式和恢复作用上的差异,定量建模了两者间的相互协作关系.通过综合双层遗传算法和FrankWolfe算法,获得模型的近似最优解.研究结果表明,与未考虑灾后恢复过程的灾前布设决策和未考虑后勤保障资源的灾前布设决策相比,最优决策可以分别降低10.96%的后勤保障资源运输成本和11.51%的加权恢复成本.后勤保障资源和应急救援设施布设数量共同影响路网的恢复效果,忽略两者间的协作关系,将会高估应急救援设施布设数量增加对恢复效果的影响.The optimization problem of multi-stage disaster response capacity of road transportation network was analyzed in order to reduce the cost of disaster response for road network and ensure the rapid connectivity of road network.A three-layer planning model for the selection of comprehensive pre-disaster emergency workstations and post-disaster road network recovery decisions was established.The differences in exhaustibility,transportation mode and recovery effect of emergency rescue equipments and logistics support resources were specially considered,and the interdependent relationship between the two was quantitatively modeled.An approximate optimal solution for the model was obtained by combining the bi-level genetic algorithm and the Frank-Wolfe algorithm.The research results show that the optimal decisions can respectively reduce the transportation cost of logistics support resources by 10.96%and the weighted recovery cost by 11.51%compared with the pre-disaster deployment decisions not considering the post-disaster recovery process and the decisions not considering the pre-disaster layout decision of logistics support resources.The quantity of logistics support resources and emergency rescue equipments layout jointly affect the recovery effect of the road network.The impact of increasing the quantity of emergency rescue equipments on the recovery effect will be overestimated if the interdependent relationship between the two is neglected.
