随着高速铁路的运载量在不断上升,未来的铁路将朝着高速化的趋势发展,铁路电气系统面临着巨大的挑战。现行阶段的电气化铁路设计工作中还有许多需要完善的地方,升级改造亟待进行。本文通过对电气化铁路的设计原则和设计要素进行分析,提出了电气化铁路的优化施工方案。 As the carrying capacity of high-speed railway is on the rise, the future of railways will move toward the trend of high-speed railway. The railway electric system faces great challenges. There are still many areas that need to be perfected in the design of the electrified railway in the current stage. Upgrading is urgently needed. In this paper, the design principles and design elements of electrified railway are analyzed, and the optimal construction plan of electrified railway is proposed.
