铁路电气化接触网工程改造施工探讨
摘要：我国电气化铁路的发展已有40多年的历史了。近年来，随着国民经济的快速发展和铁路运输需求的日益增长，铁路现有的运输能力已经很难满足当前运输的需要。为此，电气化铁路线上的列车只有不断提高运行速度来满足运输量加大的需求，而既有的接触网已经难以满足提速的要求，这就需要在既有线路的基础上进行接触网的改造施工，本文介绍了铁路电气化接触网改造工程的特点、区间线路换边拨接处接触网施工方法、如何做好铁路电气化接触网工程改造施工的措施及施工中的难点问题。

abstract: the development of electrified railway in china for more than forty years of history. in recent years, with the rapid development of national economy and railway transport demand, increasing railway existing transport capacity has been difficult to meet the needs of the current transportation. therefore, electrification railway line on the train only by constantly improve the operation speed to meet the needs of the volume increase, and the existing contact has been difficult to satisfy the requirement of speed, it needs to be in both line on the basis of the transformation of contact construction, this paper introduces the railway electrification cont
