Quantitative Research On Tunnel Safety Management And Economic Benefits Based On Accident Analysis

Increasingly numbers of tunnel construction in China and the tunnellength expanding, the security management issues become more critical.Depth study on tunnel safety management level and precisely determinestunnel safety management and cost-effective relationship which is veryurgent and realistic significance and a very wide range of applications.Papers around the tunnel safety management level to quantify therelationship between the issues and safety management and economicbenefits,This paper makes an in-depth study on accidents on tunnel safety,safety management influencing factors, tunnel safety management degree,the economic benefit.First of all, make a classification and summary on traffic accidents and fire accidents occuring domestic and foreign tunnel,analysis derived factors affecting tunnel safety management, Analysis ofpeople, cars, roads, conservation and environmental, detailed discussion ofthe tunnel safety management.Innovation proposes tunnel safetymanagement degree as quantitative indicators of the level of safetymanagement.Established the weight of the index system and itsinfluencing factors in calculation of tunnel safety management, and designevaluation of the safety management system.Demonstrated therelationship between tunnel safety management and economic benefits,and select traffic volume as an intermediate value and established thetunnel safety management and economic benefits of quantitative models.The papers take A tunnel of Q City as an example, calculate thetunnel safety management degree.According to classified Safetymanagement degree, determine the grade of A tunnel safetymanagement.Application of tunnel safety management degree andeconomic benefits of quantitative models, calculate the direct economic benefits and indirect economic benefits of the A tunnel in the Q city.Finally, using the practical application of research data validate the model.
