Abstract
Rescue stations are usually provided in very long railway tunnels. Those stations already constructed or under construction worldwide are reviewed and the basic pattern of smoke control during a rescue station fire is identified. A total of 54 model scale tests were carried out to investigate smoke control issues in rescue station fires. The effects of heat release rate, train obstruction, fire source location and ventilation condition on smoke control in the cross-passages of a rescue station were tested and analyzed. A critical smoke layer temperature near the fireproof door protecting the rescue station was investigated theoretically and experimentally and a simple equation for this temperature is obtained. A height of 2.2 m is proposed for the fireproof doors in cross-passages of rescue stations. Language: en
