捷運松山線軌道工程簡介
陳智誠 1
摘要
軌道工程係提供電聯車運行所需的完整導軌設施,如把軌道視為一獨立系統,則該系統係
由「電聯車直接承載系統」(在松山線為鋼軌)、「扣件系統」(將鋼軌扣結於道床上,且提
供適切勁度與絕緣的設施)及「道床系統」(間接承載車輛負荷並將負荷轉移傳遞至土建結構
上,於松山線為隧道仰拱)所組成。主要功能為導引車輛行駛固定路徑、承受車輛負荷並傳遞
至土建結構上,松山線且設定兼具絕緣、減振抑噪、軌道電路及負電回流路徑等功能。
本文藉由工程概述、軌道工程主要材料、軌道施工、淨空檢核等4個主題切入,大概介
紹松山線軌道工程,並將上述3個系統適時導入說明,期使讀者對松山線軌道工程能有一定
程度之認識。
關鍵詞:軌道工程、扣件系統、無道碴道床軌道、高隔振無道碴道床軌道、浮動式道床軌道
A Brief Introduction of Songshan Line's Track Work
Chen-Chih Cheng 1
Abstract
Track engineering provides a complete guild rail system for the running of electric multiple
unit (EMU). If the track work is regarded as an independent system, it is operated by the carrier
direct load system (steel rails for the Songshan line), the fastener system (rails are fixed to the track
bed by means of the fastener system, which provides adequate stiffness and insulation devices)
and the track bed system (to bear indirectly on the vehicle loading and transfer of the loading to
the civil structure, such as the tunnel invert for the Songshan line). The main function of track
work is to guide vehicles to run on a fixed route and to bear on the vehicle loading and transfer to
civil structure. Meanwhile the Songshan line’s track work also features the functions of isolation,
reducing noise and vibrations, track circuit, and negative return circle, etc.
This document is described through four subjects: a brief introduction of track work,
essential materials of the track work, construction of the track work, and clearance inspection,
and it incorporates the three systems into the discussion, in order to provide readers with a clear
understanding of the edge of Songshan line’s track work.
Keywords: track work, fastener system, direct fixation track (DF), non-ballasted track with
high isolation (NBHI), floating slab track (FST)
