ABSTRACT
ShanghaiYangtze River Tunnel runs from the Pudong Wuhaogou in the south, crossing the south channel of the Yangtze River Estuary, and ends on Changxing Island. Its total length is 8,955m. The tunnel is constructed by shield machine. The tunnel outside diameter is up to 15.0m. This tunnel engineering scale ranks top in theworld. In the shield tunneling section, its upper level is a highway tunnel while its lower level is reserved for rail transit. ShanghaiYangtzeRiver Tunnel, compared to the previous medium and small tunnels, has a more severe conflict in ventilation and fire control because of its long distance and large diameter.Any fire in a tunnel will paralyze transportation of the whole tunnel, lead socioeconomic losses and also bring serious negative effects to the society.To relieve fire hazards, the firefighting design of Shanghai Yangtze River Tunnel follows the “human-based” philosophy and puts emphasis on practicability. The design is briefly introduced hereinafter.
