| Abstract: | Based on the analysis of deformation mechanism and effect factors for deep foundation pit in soft soil, the authors raised a concept of process control for foundation pit deformation, discussed the design and construction technology and technique for deformation control and emergent measures adopted for deformation anomaly. In combination with engineering practice, the authors analyzed the deformation properties of deep foundation pit in soft soil, calculated the surface subsidence volume with the principles stratigraphic loss method. |
