摘 要

由於「捷運」路線通常會沿著現有道路佈設，以臺灣地狹人稠特性，捷運路線經
過之道路路幅可能極為狹窄，一般捷運車站及捷運高架橋立於道路中央，往往會衍生
出許多對周遭環境巨大之衝擊，像是造成鄰房的日照權、隱私權受損、捷運列車行駛
噪音對沿線鄰房之困擾、捷運高架設施對沿線5樓以上鄰房消防救災之干擾。為了使
捷運高架設施量體減小、與鄰房之間距加大，於是「疊式」高架設施的設計理念就成
了很好的解決方式。
捷運環狀線計畫第一階段為三環三線中最先執行的路線，本文係就將「疊式高架
橋」用於本計畫DF112標段之捷運設施上作簡單的說明，並介紹「疊式高架橋」在國
內、外的公共工程之運用以及運用於捷運設施之特色及優勢。藉由本文之說明，期能
讓後續高架捷運工程設計上更能系統化、模組化地規劃設計「疊式高架橋」。

關鍵詞: 疊式高架橋、狹窄路段、爬昇高架橋

Abstract
Due to MRT routes running along existing roads and Taiwan’s special characteristics of
limited land and high population density, it is very likely that the routes will pass through
extremely narrow road sections. As stations and viaducts are generally constructed in the
middle of existing roads, they often have a great impact on the surrounding environment,
such as violation of sunshine rights and privacy, noise and vibration pollution arising from
passing trains, and interference with firefighting access for buildings over five stories high.
For the purpose of minimizing MRT structure dimensions and increasing the distance
between MRT structures and buildings nearby, a ”double-decker design” has become a very
good solution to the above-mentioned problems.
This article aims to give a brief introduction of how the double-decker viaduct is applied
to the MRT Circular line Contract DF112, and the application of double-decker viaducts
in public works in Taiwan and other countries, plus the features and advantages of double-
decker viaducts applied to MRT facilities. The author hopes that the contents will contribute
to a more systematic and modular option for the planning and design of subsequent elevated
MRT routes.

Keywords: double-decker viaduct, narrow section, rising section
