摘要：我国铁路的发展日新月异，高铁如同雨后春笋般出现在神州大地的东西南北，我国的高铁技术可圈可点，已被世界认可，但是一些恶劣天还是会影响到高铁的运营，所以高铁的运营维护工作亟待完善与提高。本文以Python中的VPython模块为工具，旨在实现校园轨道交通综合实训基地无砟轨道——CRTSⅠ型双块式无砟轨道和CRTSⅡ型板式无砟轨道的三维可视化，在这个过程中了解有关于我国铁路的发展、无砟轨道的结构、Python语言三维可视化的关键技术和应用的相关知识，实现编程与模型的结合。根据所查阅的资料，我国铁路上的三维可视化技术并不多，这一方面是因为铁路是我国的后起之秀，另一方面是因为我国铁路的发展太过迅猛，运营与维护方面的技术还没来得及同步。无砟轨道的三维可视化有利于运维工作，可以准确快速的找到问题之源。

Research on key Technology and Application of 3D Visualization of Ballastless track structure
Absrtact: The development of railway in China is changing with each passing day. High-speed rail has sprung up in the east, west, north and south of China. The technology of high-speed rail in our country has been recognized by the world, but some bad weather will still affect the operation of high-speed railway. Therefore, the operation and maintenance of high-speed railway needs to be improved and improved. In this paper, the VPython module in Python is used as a tool to realize the 3D visualization of the ballastless track of CRTS Ⅰ type double-block ballastless track and CRTS Ⅱ type slab ballastless track in the comprehensive training base of campus rail transit. In this process, we have learned about the development of railways in China, the structure of ballastless track, The key technology and application knowledge of 3D visualization in Python language are used to realize the combination of programming and model. According to the information we have consulted, there are not many 3D visualization technologies on the railway in our country. This is because the railway is a rising star in our country, and on the other hand, the development of the railway in our country is too rapid. Technology in operations and maintenance has not yet been synchronized. The 3D visualization of ballastless track is beneficial to the operation and maintenance, and can find the source of the problem accurately and quickly.
