Impact Analysis of Foundation Pit Excavation on Deformation of Metro Station Nearby
Based on the foundation pit engineering adjacent to a metro station in Baoan District,Shengzhen,numerical simulation was carried out on the entire construction process so as to analyze the impact of foundation pit excavation on the structural deformation of metro station nearby.The result shows that,the deformation of the supporting structure for foundation pit is increased with the increase of the excavation depth;the horizontal deformation(towards to the pit)of the metro station structure increases gradually from the east to the west,decreases gradually from the roof to the floor,and the maximum horizontal deformation occurs at the top of the west end of No.1 air shaft structure affiliated to the metro station;the vertical deformation(upward)of the metro station structure increases gradually from the east to the west,and the maximum vertical deformation occurs in the middle of the floor of No.1 air shaft structure affiliated to the metro station.
