摘　　要：为解决地面地下物流系统耦合运作下的货运性能评估问题,根据城市物流特征刻画一体化网络设施形态,提出地下货运载具设计依据与多式联运成本测算方法,基于案例,对一体化网络运输成本、总运力、流量配置和交通安全外部效益在不同地下运载速度、发车频率和设施容量参数下的动态表现进行模拟分析。结果表明:1)路网与地下物流网络的立体协同有利于城市物流降本增效;2)与运载速度相比,地下枢纽节点的处理能力和干线隧道的通行能力对一体化网络服务水平的影响更显著。To evaluate freight performance under the combined operations of surface and underground logistics systems,integrated logistics facilities network designs are depicted according to city logistic features.Then,the design basis of underground freight vehicles and a method for estimating intermodal transportation costs are proposed.Furthermore,based on the case of Beijing,the dynamic performance of transportation costs,overall transport capacity,flow configuration,and traffic safety external benefits for the proposed integrated network under different parameters of underground vehicle speed,departure frequency,and facility capacity is simulated and analyzed.The results indicate the following:(1)The combination of road and underground logistics networks is conducive for reducing city logistics expenditures while improving transport efficiency.(2)Compared with vehicle speed,the handling capacity of underground hub nodes and the traffic capacity of trunk tunnels have a more significant impact on the service level of an integrated network.
