摘　　要：分析了传统应力场方法进行隧道结构可靠性分析存在的问题,介绍了运用超声波法和探地雷达法对公路隧道混凝土衬砌质量进行检测评定的应用情况.基于东北某现役隧道运营期间的监控量测数据,提出了一种新的结构可靠性评价方法,综合评价了该隧道的可靠性.应用表明,该方法具有实用和推广价值.所提现役隧道结构可靠性分析方法对于延长隧道使用年限,降低维护和加固费用切实可行.Discusses the problems of the reliability analysis for tunnel structure by way of conventional stress field. Discribes how the supersonic technique and geologic radar worked to detect/evaluate the concrete lining thickness and quality of an expressway tunnel. Based on the monitoring/measuring data obtained from a tunnel in service in Northeast China, a new way was proposed to evaluate comprehensively its structural reliability. The results showed that this method is highly practical and available to use for other road tunnels, and it is feasibly adaptable to lengthening the service life of road tunnels and reducing the costs for structural maintenance/ reinforcement.
