Abstract: The present invention relates to an active pressurization system making use of a platform track area upper slab of an underground train station. A track area, where a fast train and a slow train pass through an underground train station, is divided into a fast-train running space and a slow-train running space by means of a partition wall. Formed in an upper slab of the train station, there are a first and a second air-stream out- and in-flow space respectively linking to the fast-train running space and the slow-train running space. The front end of the second air-stream out- and in-flow space is provided with a first port and a first damper, while the rear end is provided with a second port and a second damper. The second air-stream out- and in-flow space is provided with a third port for venting of the slow-train running space. The first air-stream out- and in-flow space is provided with a fourth port for venting of the fast-train running space. When a fast train is running, a control panel that receives a sensing signal input from a pressure sensor for sensing pressure ensures that, on the slow-train running space where there is no slow train waiting, the first and second ports are closed and the first and second dampers are open and the third port is open and on the fast-train running space the fourth port is open, while on the slow-train running space where there is a slow train waiting, the first and second ports are open and the first and second dampers are closed and an air supplying and venting fan is driven in such a way as to supply air to the slow-train running space where there is a slow train waiting. The present invention makes it possible to solve the problem of ringing in the ears of waiting passengers by providing the fast-train running space where fast trains pass through and the slow-train running space where slow trains either stop or pass through, and by actively adjusting the supply and venting of air.
