摘　　要：研究目的:与新建高速铁路相比,既有运营高速铁路的接触网系统在提速改造的设计、施工及运营等方面更加艰巨且复杂,系统关联性强,参数变化多,论证决策难,施工运营风险高,尚缺乏系统、标准的方法和思路。本文基于国内外首次将300 km/h提速至350 km/h的成渝客专工程实例,全面剖析提速改造对高速接触网系统的要求,紧紧围绕可行性分析、系统性能提升、装备性能提升、施工质量提升、施工运维过程安全保障以及工程验收六个阶段的实施目标,从系统层级和子系统层级间的关联及需求,深入研究并提出提速改造前、中、后全过程的性能提升需求及应对策略,形成高速接触网提速改造的技术路线,为既有运营高速铁路提速改造以及更高速度铁路的工程建设、技术体系的完善等提供技术支撑、思路和范式。研究结论:(1)结合服役特点,厘清了高速接触网提速改造面临的困难及挑战;(2)基于目标需求以及运营现状,建立了高速接触网提速改造技术路线;(3)提出了高速接触网在设计、施工及运营等方面的提速改造策略;(4)本研究成果可为轨道交通领域提速提质工程建设提供指导。Research purposes: Compared with the newly built high-speed railway, the catenary system of the existing and operational high-speed railway is more difficult and complex in the design, construction and operation of speed-upgrade improvement, with strong system correlation, variable parameters, difficult demonstration, high construction and operation risk, and lack of systematic and standard methods and ideas. Based on the example of the speed-upgrade improvement project from 300 km/h to 350 km/h in the passenger transport line between Chengdu and Chongqing, this paper comprehensively analyzed the difficulties and challenges faced in the project. From the aspects of the feasibility analysis, system performance improvement, equipment performance, construction safety and quality improvement, construction operations process and engineering inspection, the requirements and corresponding strategies of the whole process before, during and after the speed improvement were studied and put forward respectively, forming the technical route of the speed-up improvement of the high-speed catenary, and providing ideas and templates for the formation of the complete technical system of the existing and operational high-speed catenary.Research conclusions:(1) Based on the service characteristics of the catenary, the difficulties and challenges faced are put forward.(2) Based on the target demand and operation status, the technical routes are established for the speed-up improvement of the existing catenary.(3) The improvement strategy is put forward in the design, construction and operation stage.(4) The research results can provide guidance for the speed-upgrade construction of rail transit.
