摘 要

臺北都會區捷運系統已通車之捷運路線多為輻射狀佈設，須有「環狀路線」將
其結合成完備之捷運路網，本計畫DF112標為臺北捷運環狀線之第一階段工程(亦稱為
「南環線」)內之重要高架工程。
本計畫路線沿中和景平路向西行，自Y8車站後約220公尺起至Y10車站後約215公
尺間，約有2.21公里須與八里─新店高架道路(台64線)共線，亦即須在現有高架橋(台
64線)東西行線間預留之3m間隙設置橋墩，並於其上方建構高度高於地面20m以上之
高架橋梁，以及於大勇街口西側Y9車站、景安路口Y10車站等兩座高架車站。
設計此段高架橋梁及高架車站時須考量如何克服施工淨寬、淨高不足之情形，並
使施工過程對八里─新店高架道路之交通衝突及既有結構影響最小呢？其需由詳細設
計及施工規劃中，包括施工方法及機具等假設工程規劃去對應處理，本文將針對上述
問題詳加說明。

Abstract
With the in-service Taipei MRT routes forming a radial network, it is necessary to
construct circular routes to connect the existing routes to make a comprehensive network.
Detailed Design Lot DF112 is a critical part of the elevated sections of the Taipei MRT
Circular line Phase I.
The route of the project runs westward along Jingping Road in Zhonghe and travels
above Bali-Xindian elevated expressway (Taiwan Provincial Highway No. 64) for about 2.21
kilometers (from 220 meters away from Station Y8 to 215 meters from Station Y10). The
design is for bridge piers to be stablished in the 3-m-wide strip between the eastbound and
westbound lanes of the Bali-Xindian elevated expressway. Based on these piers a viaduct
is to be constructed 20 meters above ground level. In addition, the project includes the
establishment of Station Y9 on the west side of Dayon Street and Station Y10 near Jingan
Road.
Considering the lack of net width and height for constructing the viaduct and the
elevated stations of the project, reducing the impact of construction on traffic and the
existing structure of the Bali-Xindian elevated expressway to a minimum is quite a challenge
that requires very careful consideration during the design stage. Coping with the challenges
requires a comprehensive design and construction plan based on theoretical planning
including construction methods, machinery, and other countermeasures. This article focuses
on all the details mentioned above.
