城市电力隧道工程属影响国家安全和经济命脉运行效益以及有重要社会影响的重大工程设施。上海电力隧道周边各种建设活动频繁,如隧道近距离穿越施工,电力隧道周边深基坑开挖等,将会导致隧道接头张开,渗漏水,严重影响到隧道的结构安全和高压电缆的安全,以上海世博电力隧道为具体工程背景,介绍了电力隧道结构安全预警指标,电力隧道运营期结构安全监测系统开发及应用。该系统已推广到上海多条电力隧道保护工程中应用,对于确保电力隧道安全运营具有重要参考价值。
The urban power tunnel project is a major engineering facility that has an impact on the operational effectiveness of national security and economic lifelines and on major social impacts. Various construction activities around the Shanghai Electric Power Tunnel are frequent, such as tunneling through the tunnels at a distance and excavation of deep foundation pits around power tunnels, which will lead to tunnel joints open and water leakage seriously affecting the structural safety of the tunnel and the high-voltage cables Safety, take the Shanghai World Expo power tunnel as a specific engineering background, introduced the power tunnel structure safety early warning indicators, power tunnel operation period structure safety monitoring system development and application. The system has been extended to a number of Shanghai Power Tunnel Protection Engineering applications, to ensure the safety of power tunnel operation has an important reference value.
