摘要:
介绍了天津地铁某盾构隧道发生透水事故后的修复技术。分析了设计中的重点难点及解决方案，其中涉及管片切割方案、临近隧道位移控制方案、冷冻施工方案、修复段衔接处接缝防水等关键内容。通过对盾构隧道透水事故后的修复技术的探讨，并根据施工实际情况，对修复方案进行总结，最终得出修复方案总体可行的结论，特别是对临近隧道的位移控制效果显著。同时也总结了设计及施工过程中遇到的问题，给出了相应的解决方案及建议。
Abstracts:
The repair technology used in a shield tunnel in Tianjin Metro after a water penetration accident was introduced, and the difficulties and solutions in the design were analyzed, relating to crucial content such as the cutting plan of the segment scheme, the adjacent tunnel displacement control scheme, the freezing construction scheme, and the joint waterproof of the repair section. Through discussion of the repair technology towards the shield tunnel water penetration accident, and according to the actual construction situation, the repair scheme was summarized, and the conclusion confirming the feasibility of the repair scheme was obtained in the end, the effect of which was especially significant on the adjacent tunnel displacement control. At the same time, the problems encountered during the design and construction process were also summarized, and corresponding solutions and suggestions were provided.
