摘　　要：介绍了隧道火灾的特点与危害,探讨了几种常用的隧道火灾探测器及其工作原理,提出了一套由手动报警按钮、数字感温火灾报警线缆和火灾报警处理器构成的火灾早期预警方案,并在隧道中进行了点火试验分析。结果表明,该解决方案是切实可行的,对隧道火灾监控设计具有一定的参考价值。The characteristics and the damages of tunnel fire are discussed. Various conventional tunnel fire detectors and their principles are also introduced. Then the capabilities and effects of the main stream tunnel fire detectors are compared. At the end of the paper, based on the development of tunnel fire detecting techniques and the design requirements of FenShuiling Tunnel, a new fire alarm system composed of manual fire button, digital temperature detecting cable and fire alarming processor is designed. The system can detect fire and give alarm at the early stage of fire. The results of the fire test experiments manifest that this solution is available for engineering application.
