Abstract: The current platform cannot realize realtime interaction of multisource data generated during shield tunneling, resulting in poor communication of crucial information and overlarge settlement. Therefore, the automatic acquisition and integration approach of multisource data are studied based on shield PLC tunneling parameters, surrounding buildings, soil conditions and monitoring data. And then an interaction platform of multisource data based on mobile application is developed to demonstrate the tunneling information in realtime for all the participants. With this platform, problems encountered during the shield tunneling can be solved by mobile interaction. The case study of shield underpassing adjacent buildings in Jinan Metro Line 3 shows the effectiveness of the realtime interaction platform of multisource data, which realizes micro settlement control of -5 mm.

Key words: shield tunneling, settlement control, multisource data, realtime interaction
