Stability and deformation control of deep foundation pits of half covered excavation subway in soft soil
A three-dimensional analysis model was established by finite element simulation to study the deformation and internal force changes of the cover plate, enclosure structure, support system, and surrounding soil during the excavation process of deep foundation pit at the Tatou Station of Fuzhou Metro Line 4 in soft soil. A corresponding theoretical basis for the excavation and support of the foundation pit project was provided. It was found that the maximum horizontal displacement of the retaining structure gradually develops downwards during excavation progresses. The maximum uplift of the base is 26.63 mm, and the surface settlement on the cover side of excavation is 60% of that on the open side. The closer the supporting structure is to the bottom of the pit, the greater the change in axial force is as the excavation of the foundation pit.
