Key Construction Technology of Shield Machine Passing through the Airport Apron in Shallow Soft Soil

Abstract:

It is a hard engineering problem for the shield machine passing through the capital airport apron in shallow soft soil. Tunneling parameters were obtained from the 50m simulation test section ahead the apron. The shield machine kept tunneling steady and balanced by optimizing the control technology of soil pressure and grouting. According to the monitoring results, the secondary and repeated grouting technology was applied timely. The deep splitting grouting technology was used when the monitoring value exceeding control standards. The settlement value was effectively controlled.
