深基坑围护位移及沉降监测中曲线回归分析法的运用技术

Application of Curve Regression Analysis Method in Displacement and Settlement Monitoring of Deep Foundation Pit Retaining Structure

在进行深圳市前海自贸区供冷站房基坑开挖及基础施工期间,对深基坑的围护结构及周边道路、建筑进行了位移、沉降及应力等的监控量测。并对监测的数据进行了曲线回归分析及预测,以便及早发现隐患,及时采取措施。进行曲线回归分析时对数据处理的技术方法进行了创新,大幅减少了计算的工作量,对其它进行监测工作的技术人员起到很好的借鉴作用。

During the excavation and foundation construction of the foundation pit of the Qianhai Free Trade Zone in Shenzhen, the monitoring and measurement of the excavation structure and surrounding roads and buildings of the deep foundation pit were carried out.And curve regression analysis and prediction were carried out for the monitoring data, in order to early detect the hidden dangers, and take timely measures. In the process of curve regression analysis, the technical method of data processing is innovated, which greatly reduces the computational workload and makes a good reference for other technical personnel who carry out monitoring work.
