Preserved Fulltext
The 18.2 km-long Yamate tunnel in Tokyo, Japan that opened to the public in March, 2015 has a unique ventilation system in it. It is divided into two sections in the middle. Each section has a transverse ventilation system and a longitudinal ventilation system, respectively. Making use of simulations, graph theory and commissioning tests for validation, the paper shows that the combined ventilation system works well for both normal and emergency situations throughout the tunnel.
