深安区间竖井混凝土支撑轴力监测分析及对策

Shen'an monitoring analysis of interval shaft concrete strut axial forces and abnormal countermeasures

依托深圳地铁7号线7302标深安区间竖井基坑工程,应用信息化施工技术,监控深安竖井钢筋混凝土支撑轴力变化情况,对所测得的轴力进行了分析和研究,总结了支撑轴力随时间、空间变化的关系,针对一些支撑轴力远大于报警值的情况,通过采取相应措施,确保了基坑围护结构的稳定和施工安全。

In this paper,based on 7302 label of Shenzhen Metro Line 7 Shen＇an interval shaft excavation engineering,application of informationbased construction technology,monitoring of deep shaft,the change of the reinforced concrete strut axial forces,the axial force is analyzed and measured by the research,summarizes the strut axial forces change with time and space. For some support axial force greater than the alarm value,by adopting some corresponding measures to ensure the stability of the foundation pit retaining structure and construction safety.
