Study on Deformation Control of Single Floor Basement Pit near Shallow Foundation Building

In order to control the deformation of single floor basement pit near the shallow foundation building in soft ground, a new foundation pit supporting structure and control technology are developed and applied in the project. The passive pile is set in the foundation pit, and the transfer beam is set between the passive pile and the supporting pile. The monitoring of the horizontal displacement of the soil, the vertical displacement of the pit outside and the settlement of surrounding houses are carried out. The results show that with the excavation, the horizontal displacement curve of the deep soil body shows a "fish belly" shape, and the displacement of the soil in the excavation process and the demolition process is not much. The horizontal displacements of the deep soil, the vertical displacements of the pit and the settlements of the surrounding houses did not exceed the warning value. The deformation of the pit adjacent shallow foundation is effectively controlled by the application of the new supporting structure and control technology.
