摘　　要：盾构法是目前城市轨道交通建设中的主要方法之一,在施工中常会穿越既有火车站股道及站房,影响铁路运营安全与地铁施工安全。当前地铁穿越施工多为双线或三线下穿,四线并行穿越在国内十分少见,相关研究尚显不足,此外四线并行穿越会增大工程风险与隐患,因此开展相关研究意义重大。探讨盾构隧道四线并行下穿火车站股道及站房的关键技术,研究成果可为同类工程参考。At present, the shield method is one of the main mays of city rail transit construction in China. Crossing the existing railway track and station is often occurred in the construction, which will influence the safeties of railway operation and subway construction. Double-line or three lines down-traversing are frequent in current subway construction, while four parallel lines down-traversing is very rare in China, the related research is insufficient, and the four parallel lines down- traversing will increase the engineering risks, so it is of great significance to carry out the related research. This paper made a discussion on the key technologies on four parallel lines of shield tunnel underpassing railway track and station house. It could be served as a reference for similar projects.
