摘 要
捷運新莊線 CK570H 區段標東門站工程，東門站是新莊線及信義線的交會車站，其中有
兩條新莊線隧道連通至中和線的古亭站，另兩條信義線的隧道是連通至淡水線的中正紀念堂
站，這四條捷運隧道由於地形地物的關係，必須在中正國中旁的杭州南路下方交叉重疊施工，
其相鄰隧道最接近處約 3 公尺，於出發井處更接近約為 1 公尺，且隧道呈 S 形的線形，最小
半徑為 200 公尺，故須先行採灌漿方式進行地盤改良施工後，再進行隧道鑽掘，且鑽掘過後，
也須保護先行完成之隧道，才可進行後續隧道施工，其困難度為國內首次在狹小區域進行多
條隧道交叉重疊施工案，希藉由本文之探討，能獲國內工程先進指教，讓工程順遂進行。

Abstract

The Xinzhuang line and the Xinyi line intersect at Dongmen Station, with two of the four
tunnels connecting to Guting Station on the Zhonghe line and the other two stretching to Chiang
Kai-shek Memorial Hall Station on the Danshui line. Due to topographical considerations, the
crossing of the four tunnels was built beneath Hangzhou South Road near Zhongzheng Junior High
School. The closest any of the tunnels come to each other is approximately three meters. As the
tunnels extend out in an S-shape with a minimum radius of 200 meters, grouting ground treatment
had to be completed before excavation. After excavation is completed, the tunnel needs to be
protected before proceeding with the subsequent construction. By examining the difficulties of
constructing Taiwan’s first-ever crossed tunnels, this article aims to gain valuable suggestions from
precursors in related domestic industries so as to assure a safe and efficient completion of
construction.

Key words: RJP high-pressure grouting, integrated management system for shield tunneling
