The research on index system and method of high-speed railway tunnel operational safety evaluation

摘要

with the rapid development of high-speed railway, China has become the world's largest number of high-speed railway tunnels. Many researches focus on quantitative assessment of design and construction stage for tunnel safety. The researches about quantitative assessment of integrating all factors for safe operation of the tunnel are few. Based on this, this paper analyzes factors of effecting tunnel operating safety, establishes the safety indicator system, and proposes evaluation method for reference.
