摘　　要：分布式光纤测振系统具有反应灵敏、监测距离长、测量空间连续、现场无需供电等优势,非常适用于狭长且封闭的隧道环境。文中利用分布式光纤测振技术,对公路隧道沿线在各时段的车流量数据进行采集和统计,同时,对隧道内每台车辆的行驶速度分别进行实时监测。以作为现有交通检测技术的有效补充,为公路隧道的运营管理提供可靠的参考依据。Distributed optic-fiber sensing system has the advantage of sensitive response,long distance monitoring, continuous measurement and passive detection. It is suitable for long and narrow tunnel environment. In this paper, the distributed optic-fiber sensing technology is utilized in traffic data collection and statistics along the highway tunnel in each period, at the same time, the real-time speed of each vehicle in the tunnel is monitored respectively. As an effective supplement of existing traffic detection technology, it can provide reliable reference for highway tunnel operation management.
