摘要: 台湾桃园国际机场联外捷运系统于桃园国际机场路段主要系以潜盾隧道方式通过,全长约7.2 km,共设置7处联络通道,其中最长之CP1联络通道开挖长度约29 m,为目前台湾最长之潜盾隧道联络通道。因其长度较长且邻近有南崁溪经过,对于联络通道之地盘改良、开挖支撑及袪水等均造成不利影响。本文说明CP1联络通道施工过程遭遇问题与解决对策,以提供后续类似工程参考。

Abstract: The route of Taiwan Taoyuan International Airport Access MRT Construction Project at the Taiwan Taoyuan International Airport section mainly passes through with shield tunnel and is about 7.2 km. Seven cross passages have been set up. The excavation length for cross passage 1(CP1) is 29 m and CP1 is the longest cross passage in Taiwan now. The CP1 was placed near river and this caused a series of impacts in the excavation, ground treatment, and dewatering. This paper describes the problems and solutions of CP1 during construction.

Key words: shield tunnel, cross passage, ground treatment, dewatering
