Correspondent: WANG Xiao-ming, E-mail: wangxming @ sohu. com) Abstract: Discusses the problems of the reliabilit anal sis for tunnel structure b w a of conventional stress field. Discribes how the supersonic technique and geologic radar worked to detect/ evaluate the concrete lining thickness and qualit of an expresswa tunnel. Based on the monitoring/ measuring data obtained from a tunnel in service in Northeast China, a new w a was proposed to evaluate comprehensivel its structural reliabilit . The results showed that this method is highl practical and available to use for other road tunnels, and it is feasibl adaptable to lengthening the service life of road tunnels and reducing the costs for structural maintenance/ reinforcement. Key words: expressw a tunnel; structure in service; uncertaint ; reliabilit ; construction monitoring , , [ 1- 4] , , , , , ,
