摘　　要：城市道路隧道随着服役期的增加,土建结构、机电设施等服役性能会逐步劣化,甚至达到危害隧道运营安全的"恶化"、"危险"等级,工程大修是必不可少的。在上海延安东路隧道大修工程实践中,结合已有隧道大修/专项整治经验,对大修的关键技术(如大修时机把握、大修必须具备的工作条件、大修后评估等)进行了分析和研究,希望能为类似隧道大修工作的顺利开展提供借鉴。With the increase of service life of urban road tunnel,the service performances of civil structure,mechanical and electrical facilities will gradually deteriorate,and even reach the"serious"and"critical"level endangering tunnel normal operation.At those conditions,the tunnel overhaul is necessary.In the overhaul practice of Shanghai East Yan’an Road Tunnel,combined with the existing tunnel overhaul/special renovation experience,the key technologies(such as the overhaul timing,necessary working conditions,post overhaul evaluation,etc.)are analyzed and studied,hoping to provide reference for the similar tunnel overhaul works.
