摘要
在富水砂层地质条件下,盾构接收施工是盾构施工过程中最主要的风险之一,也是比较容易发生事故的关键环节。文章结合工程实例,通过分析地层条件、冷冻法加固、钢套筒辅助措施、盾构接收施工等施工工艺,为后续类似工程施工提供参考。
In water-rich sandy stratum,the receiving phase of shield tunneling is one of the most critical and high-risk stages in the construction process,often prone to accidents.This paper,based on practical engineering cases,analyzes key construction techniques such as ground freezing reinforcement,steel sleeve auxiliary measures,and shield receiving procedures,providing valuable references for the implementation of similar projects in the future.
