Research On Highway Tunnel's Operating Safety Evaluation And Management System's Development

The construction and management of the China's highway tunnel started late. Especially the research about highway tunnel operation safety evaluation and management was less, and the actual work was still at the qualitative stage. Therefore, this paper established the classification of tunnel fortification, proposed a quantitative way to manage about the evaluation of the highway tunnel operation safety, and developed the highway tunnel operation safety evaluation and information management system. It provided the means and basis for the highway tunnel operation safety evaluation and management.From the current highway tunnel safety operation situation, the paper applied the engineering system and safety assessment theory, made a In-depth study about the factors of highway tunnels safety operation, proposed the classification of tunnel fortification, and gave the evaluation function and grading standards. Then the paper established a three-level tunnel operation safety evaluation index system, and gave the assessment basis and theoretical methods about the meaning and measurement of the indicators. The paper used the scale expansion method to quantity the indicators and gave the corresponding weight distribution value. Based on the results of expert evaluation and mathematical analysis theory, the paper constructed the tunnel operations safety evaluation model and achieved a quantitative assessment about the tunnel operation security. Took the GuShan Tunnel for example, the paper gave a Methodological note, and Laid a theoretical foundation for the construction of the highway tunnel operation safety management.On the basis of the theories and methods about the behavioral characteristics analysis, safety engineering and statistics, based on the distribution of accident characteristics and the causes of traffic accidents, and followed the existing policies and the highway tunnel operation safety assessment system, the paper provided appropriate preventive measures to tunnel operation safety management from the aspects of the mechanical and electrical facilities, the main tunnel facilities, the management system construction and the fire management, and gave the specific examples about the joint emergency response fire. Based on the tunnel operation safety evaluation system and the study of tunnel operation safety management Strategy, the paper made the framework of tunnel operation safety precaution, supplied the theoretical support of participation in decision-making of preventive security management operations. Finally, the paper took YangGongshan Tunnel in Jiangxi Province as an example, divided levels of security classification, assessed the operation security and tested the each of the Indicators according to tunnel operator decision-making framework of the safety precautions. And the paper conducted a detailed analysis of their problems and gave the appropriate management and disposal measures.By using of the highway tunnel operation safety Evaluation theories and methods, based on the Net Framework, adopted the C/S & B/S Hybrid System Model, applied the latest C# language of the Microsoft, and used SQL Server 2000 as the background database, the paper developed the tunnel operation safety evaluation and information management system.Finally, based on the analysis of the current situation and problems of the highway tunnel operation safety management, the paper described the administration organizations, the division of functions and the construction of safety management system. the paper gave detailed measures for tunnel maintenance and operation safety, fire control, lighting, ventilation and fire and dangerous goods transport management strategy. The paper also gave a detailed explanation about the principles, objectives, content of the highway tunnel operation safety management manual. Standardized management model should be formed in tunnel administration construction, tunnel safety management system and management strategies. To ensure the effective work of the tunnel administration and the full implementation of management and safety policy, the tunnel management departments should formulate "Safety Management Manual operation of highway tunnels" to guided the tunnel operation Safety Management.
