结合武汉长江隧道等水下盾构隧道工程，对水下盾构施工合理覆盖层厚度、盾构类型及关键参数确定进行了分析。对水下盾构施工关键技术如开挖面稳定技术、预防泥水喷发技术、防止隧道上浮技术、盾构姿态控制技术、长距离掘进及盾构水中对接技术、盾构始发与到达技术等进行了归纳。

Combined with some underwater shield tunnels such as Wuhan Changjiang tunnel, the determination of reasonable cover thickness, the shield type and key parameter selection are analyzed. The key technology of stabilizing working face, preventing muddy water eruption, preventing tunnel floating, controlling shield direction, excavating long distance, abutting joint underwater, shield launching and arriving are generalized.
