摘　　要：临近铁路既有线施工常面临因既有线不限速、接触网已通电而引起的施工效率降低、施工费用较难确定的问题。本文针对太原枢纽西南环线架梁工程,详细阐述邻近既有线共墩架梁施工重难点、施工方案、施工步骤等内容,并通过参考铁路T梁架设定额,对该工况下架梁费用进行了分析,计算出该项目由于施工降效引起的费用增加幅度,以期为后续临近既有线施工工程的技术分析及费用计算提供参考。The railway construction,adjacent to existing railway,is often faced with the problems of the construction efficiency reduction and the cost difficult to determine,which are because the existing raiway lines are not limited in speed and the catenaries are energized.This paper takes the existing girders project of Taiyuan Hub,which is on the southwest ring road of Taiyuan hub and adjacent to Taizhongyin line as a case study to expound in detail about the construction difficulty,scheme and teps of common pier erecting beam on adjacent existing railway.By referring to the raiway T-beam erecting quota,the cost of erecting beam in this project is analyzed.The increase range the cost caused by the construction efficiency reduction of the project is calculated,which could provide reference for the technical analysis and cost calculation of the projects adjacent to th exsisting railway.
