The invention discloses a vehicle-mounted retarding system for retarding tunnel pressure waves for a high-speed train, which relates to the technical field of high-speed trains and comprises a train head positive pressure retarding unit and a train tail negative pressure retarding unit of the high-speed train. A first pipeline of the train head positive pressure relieving unit is sequentially communicated with a first shutoff valve, a vacuum container, a first check valve and a vacuum pump from the train head to the train tail of the high-speed train, and a second pipeline of the train tail negative pressure relieving unit is sequentially communicated with an air compressor, a second check valve, a pressure container and a second shutoff valve from the train head to the train tail. A headstock sensor is arranged in the headstock flow guide cover of the headstock, and a tailstock sensor is arranged in the tailstock flow guide cover of the tailstock. According to the vehicle-mounted retarding system for retarding the tunnel pressure waves for the high-speed train, under the condition of the existing tunnel clearance area, the tunnel pressure waves are effectively retarded, a tunnel does not need to be transformed, implementation on a built railway line is facilitated, and the application range is wide.
