Research conclusions：Taking the connecting aisle construction of bidding 2 of Line 10 of Shanghai metro as an example, the deformation of the ground surface, the expanding and releasing pressures in the soil were monitored on the site and monitored data are analyzed in this paper. The monitored data and analysis results show the deformations can be controlled in the prescribed limit if the parameters of freezing time, expanding pressures are defined rationally and an effective soil pressure balance is established.
