盾构隧道管片上浮原因分析与对策研究

Cause Analysis and Countermeasures of Shield Tunnel Segment Uplifting

根据郑州市轨道交通1号线某盾构区间施工过程中遇到的管片上浮问题,从地质条件、同步注浆浆液、盾构姿态等方面分析原因,提出针对郑州地质条件下控制盾构隧道管片上浮的技术措施。

Aiming at the segment uplifting problems in shield tunnel construction in Zhengzhou,the paper analyzes the causes from the geological conditions,synchronous grouting slurry,and shield posture,and puts forward the technical measures on controlling shield tunnel segment uplifting according to the geological conditions of Zhengzhou.
