摘要:
贵广铁路提质改造工程是我国首次对运营高速铁路实施的全面提质改造项目,是国内首次对运营速度250km/h及以上高速铁路在维持既有主要基础设施条件不变情况下进行的提速提质改造项目,也是国内首个列控系统由CTCS-2升级改造为CTCS-3级的高速铁路项目。本文从提速适应性分析入手,系统性提出了既有高速铁路提质改造研究思路。结合贵广铁路原设计情况及既有运营现状,科学论证在现状设施条件下提速提质改造的可行性,并针对既有设备参数、指标不满足现行规范要求的情况提出解决方案。研究成果可为类似高速铁路改造项目提供借鉴和参考。
Abstract:
The Upgrading Project of Guiyang-Guangzhou High-Speed Railway marks China’s first comprehensive upgrading of an operating high-speed railway. It is the first domestic project to implement speed raising and upgrading on a high-speed railway operating at speeds of 250 km/h or above without changing the major existing infrastructure. It is also the first high-speed railway project in China to upgrade its train control system from CTCS-2 to CTCS-3. Through the adaptability analysis of speed raising,this paper systematically proposes research ideas for upgrading the existing high-speed railway. Combined with the original design and existing operation status of Guiyang-Guangzhou High-speed Railway,it scientifically demonstrates the feasibility of speed raising and upgrading within the context of the existing infrastructure,and proposes solutions to the situation that the parameters and indicators of existing equipment fall short of current specifications. The findings can provide reference for similar high-speed railway reconstruction projects.
