The project named “the rescue system and key technology of high-speed railway in perilous mountains” primarilyfocuses on current railway constructions and operations in China. To state the relationship between risk events andrisk factors, we classified the risk sources of operating tunnels of high-speed railway in perilous and mountainous area andestablished a hierarchical assessment system by using the example of high-speed railway from Guangzhou to Guiyang.According to the risk acceptance criteria and risk level standard, we analyzed the risks of operating tunnels qualitativelyand quantitatively by using AHP-Fuzzy method. As a result, the key risks were characterized and proposals were listed.Our study provides a framework for the risk analysis and management of operating tunnels of high-speed railway in perilousand mountainous area.
