前言世界道路隧道内由于交通事故或车辆起火而酿成火灾事故是不胜枚举的,特别如1949年5月美国荷兰隧道和1979年7月日本坂隧道发生特大罕见火灾其损失惨重。据英国火灾安全中心统计资料表明:地面道路上汽车火灾频率约为1次/1.7×10~7车·公里,隧道内汽车火灾频率约为1次/1.0×10~7车·公里,两者基本属于同一数量等级。道路隧道火灾中有1％是罐槽车火灾(包括汽油等可燃物和化学品罐车),平均每座隧道18年左右发生一次罐槽车火灾事
Foreword In the world of road tunnels, accidents caused by traffic accidents or vehicle fires are numerous. In particular, the huge rare fires occurred in the U.S. Holland Tunnel in May 1949 and the Japan Sakamoto Tunnel in July 1979 and suffered heavy losses. According to the British Fire Safety Center statistics show that: on the road car fire frequency is about 1 /1.7×10~7 car kilometers, the tunnel car fire frequency is about 1 /1.0×10~7 car km, both Basically belong to the same number of levels. 1% of road tunnel fires are tank car fires (including combustibles and chemical tankers such as gasoline), and an average tank tunnel fire occurs about 18 years in each tunnel
