蘇瑞麟 1

摘要
鑑於國內有許多工程重大意外事故的發生，信義線CR580A區段標工程施工團隊研議及

規劃採用各式安全合宜的管控機制，譬如「第四代無頂框深色覆蓋板」、「DOKA系統模板
及陽光大廳弧型天花組裝」、「原文湖線大安站高架下方之連續壁限高工法」、「二潛盾隧
道間距小於一個隧道直徑之型鋼內支撐近接保護」等施工法，以期能如期、如質、安全的完
成通車營運之任務。

Construction of Taipei MRT Xinyi Line Section Contract

CR580A

Jui-Lin Su 1

Abstract

In light of a number of major accidents occurring during domestic infrastructure projects, the
Xinyi line section contract CR580A construction team deliberated and planned a variety of safe

and appropriate control mechanisms. These included the fourth-generation dark composite decking
without steel rims, DOKA system templates and curved ceiling assembly for a naturally lit hall,
a height-limit construction method applied to the diaphragm walls beneath Daan Station on the
elevated Wenhu line, and proximity protection for steel structures’ internal support applied to two
shield tunnels with a between distance less than the tunnel diameter. These mechanisms ensured that
the line was completed successfully and on schedule.

Keywords: decking, height-limit construction method, proximity protection, compound
cutting blade plate, mirror frame
