Abstract

The Xinzhuang line and thd 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 200meters, 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.

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