| 摘 要： | 城市地铁深基坑开挖引起的变形给周边环境带来不利影响。地铁施工地处城市繁华区域,复杂的施工环境易导致监测数据异常。本文提出采用置信区间检验并判定监测数据异常,通过总结沉降监测数据异常的3种类型,结合工程实际进行成因分析,进而判定监测数据的正确与否。采用小波分析模型对监测数据存在误差或者粗差进行去噪处理,从而客观反馈周边环...

| Abstract: | The deformation caused by the excavation of urban subway deep pit brings harmful effects on the surrounding environment.Complex construction environment can cause the monitoring data to be abnormal.This paper uses the confidence interval to inspect and judge the abnormal of the monitoring data.We judge the monitoring data correct or not by using three kinds of settlement abnormal monitoring data and analyzing the causes of practical engineering.Wavelet analysis model has been used to deal with monitoring da... |
