Research Of Operation Safety Comprehensive Evaluation On The Tunnel Of Freeway

The start of our country freeway tunnel construction and the management are late, the safety evaluation of freeway operation tunnel in the qualitative is qualitative analysis stage, there is not quantitative diagnosis method and the system. Therefore, this paper established a set of safety comprehensive evaluation of freeway operation tunnel and developed the safety comprehensive evaluation management system of freeway operation tunnel, it has carried out quantitative appraisal and scientific management for the freeway operation tunnel.The paper introduced condition of our country freeway, put forward the application system analysis theory and the method based on the present situation of freeway operation tunnel, proposed the safety factor constitution system of influence freeway operation tunnel. After qualitative analysis to the system in the foundation of each influencing factor, unifies Delphi and preference methods, determined takes the appraisal path transportation enterprise security target the primary factor and established the safety comprehensive evaluation index system of freeway operation tunnel.Based on the safety theory of freeway operation tunnel, analyzed index of comprehensive evaluation index system of freeway operation tunnel, for example, management organization and management effect, structure health, mechanic and electrical systems, fire save system and traffic safety system significance.Reference existing country technology standard and maintenance of freeway operation tunnel, established the quality synthetic evaluation indicator system's target level qualitative and the quantitative point scale of freeway operation tunnel. Analyzed the modern safety comprehensive evaluation methods, for example, analytic hierarchy process (AHP), weighting methods and comprehensive evaluation method.Established the factor the hierarchical structure anatomic model based on AHP, used unified based on the mean square method of difference's objective evaluation law has determined the safe quality synthetic evaluation indicator system various targets weight based on the G1 method subjective valuation and the unbiased variance method. Utilizes the fuzzy mathematics quality synthetic evaluation theory and the method carries on the safe quality synthetic evaluation to the freeway operation tunnel, uses two time method of weighting to carry on quantification processing to the target, has constructed the freeway operation tunnel safe quality synthetic evaluation mathematical analysis model; Also utilized has carried on the computation based on the BP artificial neural networks algorithm to the freeway operation tunnel safe quality synthetic evaluation; Finally, the union concrete example, has carried on the practice analysis confirmation. Selected the Cronbach coefficient and the Kendall harmonious coefficient to appraise the letter to carry on the estimate. After the examination, has the remarkable significance, shows the freeway operation tunnel safe quality synthetic evaluation indicator system which the dynasty printed books topic establishes to have the good internal uniformity.Introduced the freeway operation tunnel safety quality synthetic evaluation management system management system's development goal, the development environment, the function, the main feature and the work flow, detailed expound the management system management system realizes the process; Discourse the example management system management system's application, confirmed the method validity and management system management system's usability of safety quality synthetic evaluation diagnosis of the freeway operation tunnel.
