宜万铁路地形、地质条件之复杂，集西南山区铁路之大成。建设条件之艰、难、险居我国铁路历史之最。为减少岩溶突水突石的灾害发生，首次引入了风险管理的理论并应用到实践之中，第一次提出了高风险的概念，建立了系统全面的应对高风险管理措施，其中地质勘察监理、超前地质预报、安全分级管理、水文监测、防灾报警系统等应对措施是第一次在铁路工程中进行了研究和应用。为其他岩溶隧道的风险管理提供了思路和方法。

Yichang-Wanzhou Railway is the most complicated project in southwest of China. The conditions of construction are the toughest, the most dangerous in the history of China railways. As to reduce the chance of gushing water and projecting mud soil, the theory of risk management have been introduced and applied in practice for first time. At the same time, the conception of high risks has been put forward and the systemic measures for risk management have been established. Some of the measures are studied and applied for the first time in railway projects including supervisor of geometry survey, advance geometric forecast, safe management at different grades, water monitoring and alarm system. All of these can provide experiences for other karst tunnel's risk management.
