Abstract: On the basis of analyzing and summarizing the method to calculate the ground surface settlement around the soft soil foundation pit and in the light of the deformation law of the soft soil foundation pit, the circumferencial ground surface settlement deformation of the pit is fitted in terms of exponential curves and the method is deduced to calculate the settlement deformation of the ccrcumferential ground surface of a deep foundation pit in soft soil regions that is caused by the deflection of the supporting system during excavation. Prediction is made for surface settlement through analysis and comparison of practical cases. A reliable method is put forword for the calculation of the settlement of the foundation pit projects having serious requirement on surrounding environments, which is of signifcance to enviromental protection.

Key words: soft soil foundation pit, ground deformation, calculation.
