The Beidi Tunnel is a new, shallow, urban road tunnel in Shanghai, China. It is 1780 m long and consists of two cut-and-cover parallel tubes, each carrying three lanes of traffic. It connects the middle ring road with the outer ring road between two of the busiest transport intersections in Shanghai and carries a high volume of traffic every day. For most of its length it follows the route of an overground highway. The ventilation strategy for both pollution control and smoke management in the event of a fire uses a natural ventilation system of large rectangular shafts, positioned asymmetrically above the outside lane in each carriageway. The shafts are positioned every 50 m along the tunnel, are 4 m wide by 10 m long, and discharge directly through the central reservation of the highway above, also permitting daylight into the tunnel. In 2017 and 2018, during construction, a series of full-scale fire tests and human behaviour egress studies were carried out in the tunnel. This poster summarises the egress experiments.
