摘　　要：随着上海城市地下空间的发展,地下隧道工程普遍以盾构法施工为主。盾构在施工过程中会涉及到中间风井的穿越。文章以上海市域线机场联络线3标工程大直径盾构穿越3号中间风井施工为例,阐述大直径盾构直接穿越中间风井的施工工艺以及过程中需注意的要点,为其他类似工程提供参考借鉴。With the development of urban underground space in Shanghai, shield tunneling is the main method for underground tunnel construction. During the construction process, shield tunneling inevitably needs to pass through the middle air shaft. The article takes the construction of shield tunneling through the No. 3 air shaft of the Shanghai Metro Airport Link Line Section 3 project as an example to explain the construction technology and key points to be noted during the process of large-diameter shield tunneling through the middle air shaft, providing reference for other similar projects.
