地铁车站深基坑围护结构变形监测与数据曲线回归分析

Deformation Monitoring and Data Curve Regression Analysis of Retaining Structure for Deep Foundation Pit of Subway Station

为了确保地铁车站深大基坑围护的结构安全,需做好沉降及变形的监控量测,数据分析与反馈,以便指导现场施工,及时发现及排除安全隐患,确保地铁车站建设的施工安全。本文结合某地铁车站,阐述了基坑围护结构的监控量测方案,及对监测数据进行曲线回归分析的方法,并根据计算结果分析及评估基坑围护结构设计的合理性和结构的稳定性。希望能够给类似其它地铁车站深基坑的安全施工提供借鉴及指导作用。

In order to ensure the safety of deep foundation pit support for subway station, it need to do a good job of the settlement and defor^nation monitoring, data analysis and feedback, so as to guide the construction site, timely find and eliminate security risks, ensure the safety of subw-ay station construction. Combined with a subway station, this paper expounds the monitoring test scheme of retaining structure, and method of curve regression analysis of monitoring data, and according to the results, analyzes and evaluates rationality of foundation pit retaining structure design and the stability. It is hoped that this paper can provide reference and guidance for the safety construction of deep foundation pit of other metro stations.
