沉管隧道的各管节通过接头连接，端钢壳作为安装GINA止水带和OMEGA止水带的载体，是沉管隧道接头的重要组成部分，端钢壳的安装精度和工效在沉管隧道建设中具有重要作用。通过对一次成型、二次成型端钢壳施工工艺的分析，阐述了两种工艺在适用范围、安全、质量等方面的优缺点。一次成形端钢壳施工工艺作为一种新型工艺，对于管节预制数量多的沉管施工更具优势。
沉管隧道的各管節通過接頭連接，耑鋼殼作為安裝GINA止水帶和OMEGA止水帶的載體，是沉管隧道接頭的重要組成部分，耑鋼殼的安裝精度和工效在沉管隧道建設中具有重要作用。通過對一次成型、二次成型耑鋼殼施工工藝的分析，闡述瞭兩種工藝在適用範圍、安全、質量等方麵的優缺點。一次成形耑鋼殼施工工藝作為一種新型工藝，對于管節預製數量多的沉管施工更具優勢。

All tube sections of immersed tube tunnel are connected by joints. The steel shell, as the carrier for erection of GINA waterstop and OMEGA waterstop, is an important part of the tunnel. The installation precision and efficiency of steel shell play an important role in the immersed tube tunnel construction. Through analyzing the steel shell construction technologies of one-step molding and two-step molding, we introduced the virtues and flaws of two technologies in aspects of applicable scope, safety, quality, etc. The steel shell construction technology of one-step modeling as a new technology has more advantages for the immersed tube which has a large number of tube prefabrication.
