高速铁路接触网无交叉线岔工程实践与研究

无交叉线岔是高速铁路接触网较为复杂、技术要求较高的单元。我国开始大规模高速铁路建设伊始,因国内各设计单位设计理念不同,国内高铁无交叉线岔定位存在大拉出值布置和小拉出值布置两种方式。十余年高铁运行实践证明,这两种方式均满足高铁安全运行要求,但在安全可靠性方面存在差异。本文收集和分析了国内外高速铁路无交叉线岔最新理论研究和工程实践成果,为进一步完善我国高铁无交叉线岔设计提供参考。

Non-crossing type overhead crossing is a complex unit with high technical requirements for OCS of high-speed railway.At the beginning of large-scale high-speed railway construction in China,due to different design concepts of domestic design companies,there are two modes for arrangement of large stagger and small stagger for the location of non-crossing type overhead crossings of high-speed railways in China.The operation practice of high-speed railway for more than ten years has proved that these two modes can meet the requirements of safe operation of high-speed railway,but there are differences in the degree of safety and reliability.This paper collects and analyzes the latest theoretical research and engineering practice results of non-crossing type overhead crossings for high-speed railways at home and abroad,so as to provide reference for further improving the design of non-crossing type overhead crossings for high-speed railways in China.
