T.Y. Lin International (TYLI Taiwan) provided civil engineering services for the Xinzhuang Line Line project, Design Lot dk195, for the Taipei Mass Rapid Transit System in Taipei City, Taiwan.

The Xinzhuang Line Line is a high-capacity underground extension of the Zhonghe Line in Taiwan and Taipei’s first metro line to cross under the Tamsui River. At a length of 19.7 kilometers, the line runs from Guting, through transfer stations on the Nangang and Tamshui line, and terminates in Xinzhuang. The line includes 16 underground stations and one maintenance depot.

The scope of work for TYLI Taiwan included three underground cut-and-cover stations: the Xinzhuang (O2), Touchien Chuang (O3), and Hsiense Temple (O4) stations, and associated bored tunnels.

Project Highlights:

  • The 4000-meters-squared transfer facility, with a 2-story parking lot, is located near entrance A of the O3 station.
  • There is a 141-meter-long crossover section located west of O2 station, and an L-shaped pedestrian underpass connected to entrance A of the O3 station at the junction of S-Yuan Road and Zhong Zheng Road.
  • Light structures and transparent architectural design concepts were adopted for the station entrances, reflecting the local characteristics of each station and corresponding to the chosen public art themes.
  • The underground stations are connected by two 3.4-kilometer-long single-track parallel bored tunnels. Nine cross passages are placed between the two parallel tunnels.
  • Precast concrete segmental lining was used for the bored tunnels, except at the junction of the bored tunnels and cross passages where steel segmental lining was used.
