哈大高速铁路转临时便线接触网过渡设计研究

以哈大高速铁路转临时便线接触网过渡设计为背景,着重论述高速铁路转临时便线接触网过渡设计中发现的新问题及处理方法。通过对多个设计方案在技术标准、对运营高速铁路的影响、施工难度、经济评价等方面对比分析,提出准确定位高速铁路临时便线标准,避免在运营高速铁路线路两侧设置临时便线用接触网支柱以及灵活运用永临结合设计原则的设计思想。

Design Research for Overhead Contact Line System's Transition from High-speed Railway to Temporary Detour

The design for overhead contact line system's transition from the Harbin-Dalian high-speed railway to a temporary detour was taken as an example in this paper. This paper emphatically discussed how to deal with the problems that were recently found in design for overhead contact line system's transition from high-speed railway to temporary detour. After comparative analysis on multiple design schemes from some perspectives such as technical standard,influence on high-speed railway's operation, difficulty of construction,economic evaluation and so on,this paper proposed the following design ideas: the standard of temporary detour connecting to high-speed railway should be accurately determined so as to avoid installing temporary detour's catenary pillars on either side of high-speed railway; and the design principle of combining temporary with permanent should be flexibly utilized.
