摘要
本文结合长沙地铁管片拼装的工程实例，从当前管片的组合形式入手，分析封顶块点位对隧道防水、管片破损、隧道线形、隧道结构受力产生的影响，对合理设置封顶块点位确保盾构隧道施工质量有一定的指导意义。
This paper combined with the engineering example of Changsha Metro segment erection, starting with the combi-nation of current segment, analyzes the influence of completed block point effect on tunnel waterproof, segment damage, tun-nel alignment, tunnel structure force, and has certain guiding significance in set ing reasonable block point to ensure the qu-ality of shield tunnel construction.
