摘　　要：为研究设置危险品运输专用道对危险品运输网络抗毁性的影响,寻找利于运输网络正常运行的危险品车辆比例,建立了设置专用道的危险品运输网络级联失效模型;对专用道设置前后的算例网络分别进行级联失效仿真研究,并分析不同负载能力和危险品车辆比例下的网络抗毁性变化。结果表明:专用道的设置会降低危险品运输网络的抗毁性,且存在某个危险品车辆比例区间,在该区间内危险品运输网络具有较高的抗毁性。In order to study the impact of the construction of the dangerous goods lane on the damage resistance of the dangerous goods transport network,the proportion of dangerous goods vehicles conducive to the normal operation of the network was found,and the cascade failure model of the dangerous goods transport network was established.The cascade failure simulation of the network before and after the lane is set up is carried out,and the change of the network resistance under different load capacity and proportion of dangerous goods vehicles is analyzed.The results show that the establishment of special lanes can reduce the damage resistance of dangerous goods transport network,and there is a certain proportion of dangerous goods vehicles in the region,in which the dangerous goods transport network has a high damage resistance.
