Abstract: Aiming at the problem that node failure caused by the emergencies will seriously affect the efficiency of the subway operations, to solve the problem, an analysis method was proposesed to analyze the vulnerability of subway network based on complex network theory. By taking current Wuhan subway network for example, by used of Pajek tool, a topological structure of the current city subway network was established,which covered 58 stations and 57 connecting edges to systematically analyze the static and dynamic vulnerability levels of urban subway network in case of facing random attack and purposeful attack . The results show the successive purposeful attacks on nodes will cause most damages to railway network, random attacks will cause secondary damages and purposeful attack on single node point will cause minimum damage to the railway network. The node point of bigger degree is the vulnerable point in the line network.
