Abstract: A method for a degraded train emergency rescue includes: obtaining a communication status of a private communication network that connects a train to a ground system, to a front train, and to a rear train; determining whether the private communication network fails based on the communication status; in response to determining that the private communication network fails, restarting an on-board private network switch of the train; determining whether the private communication network is recovered after the on-board private network switch is restarted; in response to determining that the private communication network is not recovered, starting an on-board public network switch of the train, and establishing public network communication between the train and each of the front train and the rear train; and performing an emergency rescue through a public network.

Abstract: The invention provides a whole-granulation steel slag pavement base course material for a heavy-load pavement, which is prepared by uniformly mixing dry materials with water. The dry materials include a binder and a steel slag aggregate. The percentages in total mass of the binder and the steel slag aggregate are as follows: the binder is 3.4% to 5.0%, and the steel slag aggregate is 95.0% to 96.6%. The binder is prepared by mixing cement with steel slag micropowder according to a certain proportion, wherein the mass percentages of the cement and the steel slag micropowder are as follows: the cement is 70% to 90%, and the steel slag micropowder is 10% to 30%. The water accounts for 5% to 6% of the total mass of the dry materials.
