Abstract


With the great development of modem transportation, China has become the country which has the most projects of the tunnel. However, because the tunnel structure safety is influenced many factors, the people painstakingly has not been synthesized, since long ago to the tunnel structure safety to each factor the mensurable evaluation method.Based on this, the thesis elementarily explores assessment of the tunnel structure security, according to the feature of the tunnel structure.The thesis obeys the general procedure and theory of security assessment, adopts the means of combination of fixed quality and fixed quantity, selects the assessment guideline which can relatively reflect the status of tunnel structure security. The essay constructs assessment guideline system by adopting arrangement analytical method, as well as makes use of the authority of all items confirmed by experts investigating method. Afterwards, this essay sets up the third class fuzzy comprehensive judge model, with Fuzzy Comprehensive Assessment as the theoretical foundation. Taking into account that the intensity of concrete is influenced by time, the paper takes the intensity of concrete in liner laying as the dynamic assessment guideline of the tunnel structure safety, as well as predicates the concrete intensity even value of the tunnel structure in any time unit, in order to achieve dynamic assessment. Finally, The thesis compiles "TSDE" system with the C# programme language, and put the dynamic assessment system and judge method into the liner-built structure security assessment of the Bazhong-Pengshan railway Tieshan tunnel and analyzes the security of the liner-built structure of this tunnel, adopting the way of value simulation. After that, this thesis proves the dynamic assessment and judge method feasible and correct, according to the result of comparing the two. The thesis has constituted the safety dynamic evaluation system of the highway tunnel structure, which is simple, convenient and practical. Analysis and prediction to the security of highway tunnel structure with the measure method of the tunnel comprehensive judge system has stimulated the standardization and signification of the highway tunnel structure security management.
