Taking the project of a newly-built subway shield tunnel interval close underpass operating intervals in Tianjin as the background,the use of numerical calculation methods on the operating intervals of the deformation of the prediction analysis is carried out.According to the operating interval displacement change rule,in addition to conventional grouting and other construction measures,the crossing section is constructed by the mud control method.The actual monitoring data is analyzed and found that the monitoring data are less than the predicted value of the analysis,and the trend of change is basically the same.The settlement after construction meet the relevant specifications.The deformation can be controlled effectively with the construction measures by the mud control methold.
