摘　　要：长大公路隧道是重庆市交通基础设施的核心,近年来结构(设施)损坏事故时有发生,提高运营安全保障能力已成为亟待解决的问题。对重庆市长大隧道结构(设施)损坏事故展开调查,分析事故原因、形态及风险源,从结构健康维护与防灾救援体系两方面调研结构安全保障体系现状,明确安全保障制度、措施及技术有效性与现实需求,分析其面临的难题与挑战,结合新兴科技提出长大公路隧道灾害防控、应急救援等运营管理创新制度、措施和技术研发应用,建议推出三大行动计划,构建以“健康监/检测,先进维护,智慧防灾,快速应急,综合评估”为核心的安全保障体系,助力重庆市建设成为国际性综合交通枢纽和国家(西部)科技创新中心,促进成渝地区双城经济圈建设,推动我国综合立体交通网安全发展。Long and large highway tunnels are the core transportation infrastructure in Chongqing. In recent years,accidents relating to structural(facility) damage occur from time to time, so it is urgent to improve the operational safety and security capabilities. In this study, the accidents relating to structural(facility) damage to long and large tunnels in Chongqing were investigated, and the cause and form of accidents and risk sources were analyzed, the status of structural safety and security system was investigated and researched in terms of structural health maintenance and disaster-prevent and rescue system, the safety assurance system, measures, technical validity and real demands were defined, the difficulties and challenges suffered were analyzed, and the innovative operation management system and measures for disaster prevention and control, emergency rescue, etc. of long and large highway tunnels and the technical R&D and application were proposed in combination with emerging technologies. It is recommended to put forward three major action plans to build a secure guarantee system centered on "health monitoring/detection, advanced maintenance, smart disaster prevention, rapid emergency response, and comprehensive evaluation",help Chongqing become an international integrated transportation hub and a national(west China) science and technology innovation center, promote the construction of a dual-city economic circle in Chongqing and Chengdu, and boost the safe development of our integrated three-dimensional transportation network.
