Abstract:
The technical status of the tunnel structure directly affects its performance during service stage, and the commonly used the worst subsection method can not meet relevant requirements. Thus, it is very important to establish a set of rational and effective evaluation method. In order to optimize the existing evaluation method for the technical status of tunnel structure and the integrity of evaluation values, the stateoftheart of the technical status evaluation of the tunnel structure in China and abroad is indepth analyzed; and then the modifying method based on the worst subsection method is proposed in accordance with “common reflection principle” and “security principle”; the relationship between subentries of tunnel construction with every index are refined; finally, a comprehensive, quantitative and qualitative evaluation method is established. By doing these, corresponding relationships between values from existing standards and deduction values from modifying method can be found, and a quantitative evaluation model for technical status of the tunnel structure is obtained. The effectiveness of the modifying method is verified by demo project.
Key words: tunnel, technical status of structure, the worst subsection method, common reflection principle, security principle
