摘　　要：结合盾构隧洞管片设计工程实例,采用修正惯用法对下穿海域段隧洞管片进行结构分析,得到管片结构变形、内力分布规律;采用多道橡胶密封垫,结合衬砌结构自防水、外注浆等形成管片防水体系,防水效果良好,可为同类型跨海盾构隧洞设计提供参考。Based on the example of shield tunnel engineering,the modified inertia method is used to analyze the structure of the tunnel segment passing through the sea,and the deformation and internal force distribution of the segment structure are obtained;The use of multiple rubber sealing gaskets,combined with self waterproofing and external grouting of the lining structure,forms a segment waterproofing system with good waterproofing effect,which can provide reference for the design of similar cross sea shield tunnels.

关 键 词：管片 修正惯用法 防水体系
