| 摘 要： | 根据目前中国公路隧道建设的实际状况和技术水平,建立了公路隧道防火安全等级体系。提出了影响公路隧道防火安全等级的5个因素和4种关系,认为公路隧道防火安全等级的划分必须同时考虑隧道长度和交通量。选取隧道的特征长度分别为0.5、1.0、3.0、5.0、10.0 km,隧道的断面交通量按照高速公路的最低要求取10 000 veh/d,将公路隧道防火安全等级从高到低划分为5个等级,并给出了与之相对应的防火设施配置和运输危险物品时的交通控制表。

| Abstract: | Based on the actual status and technique level of highway tunnel construction in China,the system of fire prevention safety grades in highway tunnel was established.Five factors and four relations affecting fire safety grades of highway tunnel were put forward.The length of tunnel and the traffic volume must be considered in classifying the safety grades of highway tunnel.The safety grades were divided into five grades with regarding 0.5,1.0,3.0,5.0 and 10.0 km as characteristic length of tunnel,and 10 000 veh/d was selected as the lowest traffic volume.The fire prevention facilities collocation table and traffic control table for transporting dangerous goods were presented.2 tabs,2 figs,12 refs. |
