| With the sustained and rapid development of the national economy, China's expressway construction has entered a new stage of development. In previous years, due to economic conditions and technological level of the lower limit of the highway tunnel construction of more and more importance for the people. At present, up the road to the development of the tunnel, traffic density, operating speed continuously improve tunnel security situation is worrying and, more importantly, the severe security situation in the tunnel has not yet attracted sufficient attention. At present, our country has not a more systematic evaluation of tunnel safety norms in the industry. The existing "safety evaluation of highway projects guidelines" are given only a simple type of evaluation framework for thinking, maneuverability is very limited. Therefore, the system safety assessment of highway tunnel increasingly more important.This article first reviewed the security situation at home and abroad highway tunnel, there is the problem of tunnel safety in Europe to introduce the concept of evaluation, and secondly, on the highway tunnel to carry out a detailed traffic analysis, clarifying the impact of tunnel safety factors, and then, Construction of the tunnel safety evaluation index system, combined with China's specific characteristics of the road tunnel, select the fuzzy ? comprehensive evaluation method for the evaluation of this article. Finally, along the highway in Ningxia tunnel with a security assessment to verify the evaluation of the rationality and feasibility.I hope this paper, the evaluation of methods, means for improving tunnel safety and to lower the risk of making a certain contribution to the tunnel for future tunnel construction, alterations to provide some help, in order to provide decision-makers from the construction of the tunnel. |
