The invention discloses an air route traffic flow network cascade failure chain propagation modeling method, which comprises the following steps of: constructing an air route-traffic flow cooperative operation double-layer dynamic network which comprises an air route traffic flow dynamic topology network and an air route cascade failure dynamic network; establishing a traffic flow redistribution model, and distributing the traffic flow in the invalid leg to an adjacent leg in normal operation; establishing a failure propagation-oriented air route network traffic flow evolution dynamic model, and updating an air route traffic flow dynamic topology network; establishing an air route network cascading failure chained propagation model, and quantizing and representing the model as a route segment comprehensive state index; and according to the route segment comprehensive state index and a preset condition, carrying out route cascade failure dynamic network updating judgment and iteration. According to the method, the air route failure chain type propagation effect pre-judgment capability can be remarkably improved, and important support is provided for actively preventing air route cascade failure, ensuring continuous and safe aviation and improving the operation efficiency of an air route network.
