Fire risk assessment model based on evidence theory for long-highway tunnel
Zhisheng Xu · Journal of Railway Science and Engineering · 2010
In this paper,the characteristics of long-highway tunnel fire and the causes of long-highway tunnel fire were studied.The basic requirements on safety equipment and its operation based on the summary of fire-preventing and rescue strategies at existing long-highway tunnels both at home and abroad was analyzed.Then a index system with general evaluation significance was proposed.It have 5 first-grade assessment indexes,including tunnel fire safety systems,transportation and management policy,tunneling technology condition,emergency relief ability and community-supporting capability.The 5 assessment indexes in the given index system should include all the 23 secondary assessing indexes altogether.This paper have built the long-highway tunnel risk assessment model based on evidence theory and show its application processes through examples by making use of the features that evidence theory processes fuzzy information.
