京港澳高速公路改扩建工程中出现的特殊路堑既有别于一般路堑,也有别于公路隧道,由于其结构形式的特殊性,在防火救灾方面需要进行针对性设计。从系统工程角度提出防火救灾对策应按照“防灾→减灾→救灾”的思路展开,形成一个环环相扣的安全链,以确保特殊路堑段安全、畅通运营,强调指出“防灾”是基础,“减灾”是关键,“救灾”是重点。
Due to the particularity of its structural forms, special cutting in the reconstruction of Beijing-Hong Kong-Macau Expressway is different from the common cutting and the tunnels. Therefore, it is necessary to carry out targeted design in fire prevention and disaster relief. From the system engineering point of view, fire prevention measures should be made according to the idea of “Disaster Prevention → Disaster Reduction → Disaster Relief” to form an interlocking safety chain so as to ensure the safe and smooth operation of the special cutting section, stressing that “disaster prevention ”Is the foundation, “ disaster reduction ”is the key, “ disaster relief ”is the key.
