对地铁隧道联络通道防火门变形脱落引发事故的思考

摘要

The paper analyses the properties of piston wind and the specific influence of piston wind on the fire door in subway, then analyses the cause of the accident through review of the accident fire door's drop in subway and emphasizes the importance of contact channel and its fire door in subway. Then it is concluded that testing for the wind pressure on the fire door in subway is necessary.%通过对地铁活塞风作用下地铁隧道区间联络通道防火门脱落事件回顾,强调了联络通道及防火门的重要性,分析了地铁活塞风性质及其对联络通道防火门的具体影响及事故原因,做出了需要对防火门进行压力测试的结论.
