分布式光纤传感技术在城市综合管廊的应用

摘要

地下综合管廊的建设刚刚在我国起步，其消防建设、智能化建设与管理方面普遍存在依据不足等问题，针对地下综合管廊工程中的火灾探测系统和隧道形变监测系统进行功能性分析，讨论其应用方案和技术难点，提出采用分布式光纤传感技术对地下管廊火灾和形变进行实时在线监测。%The construction of underground composite pipelines has just been started in China and there still are not enough bases for fire-fighting construction and intelligent construction and management. The functions of fire detection system and tunnel deformation monitoring system for underground composite pipeline engineering are analyzed, it’s application scheme and technological difficulties are researched, and distributed optical fiber sensing technology is proposed for real-time online monitoring of fire and deformation for underground composite pipelines.
