摘　　要：受既有隧道净空条件、衬砌强度及限界等限制,电气化改造中的隧道工程设计方案往往是整个项目的重难点,也影响着整个工程的施工风险和工程投资。论文从隧道限界、材料标准、衬砌缺陷及病害等情况对西岭隧道进行分析,对限界、衬砌结构、耐久性、电气化措施等工程改造方案进行了比选研究,提出既有隧道电气化改造设计原则和方案。Restricted by the existing tunnel headroom conditions,lining strength and limits,tunnel engineering design in the electrification transformation is often a major difficulty for the entire project,which also affects the construction risk and project investment of the entire project.In this paper,the current situation of Xiling Tunnel from tunnel limits,material standards,lining defects and diseases,etc.is analyzed,and engineering transformation programs such as limits,lining,durability,and electrification measures are compared and studied,and the design principles and programs for electrification transformation of existing tunnels are proposed.
