Abstract

Monitoring data is the important signal for safety situation decision of shield method construction. This paper analyzes the abnormal types appearing in safety monitoring data of shield method construction, and points out its caused by the environmental quantity anomaly, structure form change, misreading mistake, instrument error, and human negligence. Based on the test and analysis of the abnormal monitoring data, it considers the monitoring data as abnormal value if the monitoring data beyond the confidence interval. And then uses the theoretical model to eliminate the observation error and systematic error. Furthermore, this paper analyzes the reasons of abnormal of the shield method construction settlement monitoring data, displacement monitoring data, shaft force monitoring data, deep horizontal displacement monitoring data, the water level monitoring data according to theory above.
