Ventilation of Partially Submerged Subway Stations

Standards and guidelines for transit station fire protection are well established for enclosed stations attached to underground tunnel networks, and above ground stations that do not trap heat or smoke in evacuation paths during a fire event. However, partially submerged stations pose a problem for the designer as they are not readily ventilated by conventional systems, but still do not qualify for treatment as above ground station under NFPA 130. AECOM Tunnel Ventilation has designed a ventilation system for a partially submerged station that includes innovative ventilation elements that satisfy safe evacuation standards, while maintaining the open architectural feel of an above ground open station. Modeling results will be presented that demonstrate challenges inherent in the station design, and solutions including mesh optimization, wind driven elements, and novel fan placement. The resultant solution is applicable to other locations and permits the design of stations that have open architecture while still protecting safe egress during a fire event.
