Research on the Intelligent Monitoring Method of Formation Deformation in Subway Shield Construction
In order to improve the accuracy of the formation deformation monitoring results of subway shield construction and ensure the construction safety,an intelligent and efficient intelligent monitoring method is proposed.First of all,understand the construction of the information and site conditions,the reference points and deformation monitoring points.Secondly,sensors are installed at the datum point and deformation monitoring points to collect formation monitoring data.The monitoring data were preprocessed and the deformation characteristics of shield construction were extracted.On this basis,the monitoring and early warning value is set to monitor the dynamic change of subway shield construction strata in real time,the early warning level of stratum deformation is determined,and the monitoring and early warning information is sent.The experimental analysis results show that after the application of the proposed intelligent monitoring method,the deformation displacement monitoring value of each measuring point is closer to the measured value,and the monitoring accuracy is significantly improved.
