公路遂道中监控系统设计及设备的选择

Design of the monitoring system and selection of its equipment for road tunnels

三峡工程对外交通专用公路隧道多而长，监控系统设备使用环境恶劣，必须对该系统的关键技术、国内公路隧道监控系统现状、工程投资和设备选择等几个方面进行分析、探讨。在对大量考查资料和技术数据分析的基础上，提出了三峡工程对外交通专用公路隧道的监控系统设备选择原则是：满足招标文件，性能先进．性价比好。

The environment for using the monitoring system for road tunnels is worst for longer Three Gorges accomodation road and through more mountains. Therefore, several aspects should be analysed and investigated such as the key techniques, the present status of monitoring systems, project cost and equipment selection for road tunnels in China. The principles for selection of the monitoring system of Three Gorges accomodation road tunnels are put forward based on analysis of lots of both investigative and technical data.
