自然通风方式城市水平隧道安全距离研究

Study on the City Tunnel Safety Distance Under Natural Ventilation

在隧道事故后无通风系统排风的条件下,对人员逃生的忍受程度进行一组数据的分析,通过得到的逃生距离的数值进行讨论,以此确定隧道依靠自然通风的最长距离。超出此距离的应该进行相关安全逃生通道及通风设备的设置。

This paper conducts analyses on a set of data of the endurance degree of the escape under conditions of non exhaust ventilation system after the accident,discusses the safety escape distance resulted in and so the longest escape distance under natural exhaust ventilation is determined.Beyond this distance should the safety means of escape and ventilation equipment be set up.
