The invention provides a subway station active and passive anti-floating structure which comprises an active anti-floating device and a passive anti-floating device, the active anti-floating device comprises a water guide ditch, a water filter pipe, an overflow pipe, a water collecting pipe, a pre-buried water drainage pipe, a water drainage pipe and a water collecting pit, and the water guide ditch and the water filter pipe are arranged between a subway station bottom plate and a rock-soil foundation; the overflow pipe is fixed to the inner side of the fender post, the water collecting pipe and the pre-buried drainage pipe are arranged in the side wall of the subway station, and the sewer pipe and the sump are located in the subway station. The passive anti-floating device is an uplift pile. According to the pressure-limiting drainage active anti-floating device, only buoyancy under the high water level in the wet water period is removed, the water level is controlled to be below the pressure-limiting water
