Abstract:This paper presents the robustness analysis of the interdependencies between urban critical infrastructures (CI) against cascade failures. An analytical approach based on the dynamic percolation theory was introduced to investigate the multilayer interactional CI networks and to predict the urban calamity spreading as illustrate with example of China. The synergetic effect of the functional and geographical interdependencies between the networks on cascade failures of CI was studied by comparing four relevance patterns: no interdependency, the functional interdependency, the geographical interdependency, and the functional with geographical interdependency, where three different attack strategies were simultaneously considered. The results indicate that the geographical interdependency has a remarkable influence on the robustness of networks compared with functional interdependency. Moreover, excavating the scope and extent of the impact of these interdependencies, one can also find that the power network basically governs the cascade failures of global systems in contrast with water or gas network.
