Risk Assessment on Operating Tunnels of High-Speed Railway in Perilous and Mountainous Area

ABSTRACT

The project named “the rescue system and key technology of high-speed railway in perilous mountains” primarily focuses on current railway constructions and operations in China. To state the relationship between risk events and risk factors, we classified the risk sources of operating tunnels of high-speed railway in perilous and mountainous area and established 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 qualitatively and 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 perilous and mountainous area.
