| In recent years, with a large number of the mountainous area highway construction,and then present a long tunnel, tunnel group of sections in the mountainous areahighway also can be seen everywhere. The construction of the tunnel group of promotedthe highway to develop, give people travel brought great convenience. But the tunnelhas become the main group of the mountainous area highway traffic safety of thebottleneck, therefore, how to ensure the tunnel group of traffic safety, make themountainous area highway to develop its the biggest social and economic benefits, ithas become a new and extremely important research subject. This has many experts andscholars from different angles, direction in the task, also have achieved remarkableresults. When in the mountainous area highway tunnel road safety evaluation of linearwork still is in start level, also have no a scientific, correctly, and applicable evaluationmethod.This paper introduced the concept of tunnel group, analyzes the impact of themountainous area highway tunnel sections of the security of the people-car-road andenvironmental factors, and put forward the tunnel group of security research, thedivision of the period.This paper demonstrates the linear conditions on the mountainous area highwaytunnel sections of the influence of the security, on the analysis of the existing evaluationmethod is proposed on the basis of a more scientific and reliable, and use of the fuzzyevaluation method. The evaluation and determine the mountainous area highway tunnelsections of the evaluation index, established the mountainous area highway alignmentsafety evaluation index system, use ahp to the index weight coefficient, determined theindexes of the membership function, in this paper, the evaluation of the mountainousarea highway alignment safety fuzzy mathematical model. And applying to entities ofengineering, evaluates the chongqing xiang highway tunnel sections of the wuwaterway linear safety, its evaluation conclusion for "safety general". |
