摘要
针对长平高速公路虹梯关特长隧道监控设备运行时间长、部分设备老化损坏、视频监控系统为标清系统、图像清晰度低、不能获取准确事故细节信息、存在一定安全隐患的问题,依据隧道提质升级行动技术指南及现行公路隧道附属设施设计相关规范要求,提出了虹梯关隧道监控系统改造工程设计方案,以提高隧道运营安全性,进而提高高速公路的通行效率。
In view of the long running time of monitoring equipment in Hongtiguan extra long tunnel of Changping Expressway,some equipment are aging and damaged;The video monitoring system is a standard definition system,with low image definition,unable to obtain accurate accident details,and there are some potential safety hazards.According to the technical guide for tunnel quality improvement and upgrading and the requirements of relevant specifications for the design of ancillary facilities of highway tunnel,this paper puts forward the design scheme of Hongtiguan tunnel monitoring system reconstruction project,in order to improve the safety of tunnel operation and then improve the traffic efficiency of expressway.
