Analysis on Deformation Control of Deep Foundation Pit Support on Soft Soil Foundation
This paper takes a new commercial housing project as an example to study the deformation control of deep foundation pit support on soft soil foundation of residential buildings.The results show that the soil deformation is the largest at the foot of slope,and the cumulative depth is 9.12～10.4mm.The maximum displacement of the measured retaining wall is 6.3mm.The maximum value of settlement monitoring for hilltop buildings is 6.1mm,and the actual settlement value is slightly larger than the numerical analysis results,which does not exceed the monitoring warning index.The maximum value of horizontal displacement of buildings is 4.3mm,which meets the requirements of building support deformation control.
