Analysis of Foundation Pit Deformation Monitoring Results about Xia Shengou Station in Shenyang

Abstract

In the northeast of China,the research of subway foundation pit is still infancy,which needs enriching. This paper relies on the deep foundation pit engineering of Xiashengou Subway Station in Shenyang. Through the analysis of deformation foundation pits to study deformation characteristics.Through the monitoring data,we can know that combined the bored and steel support the deformation of the retaining structure and the ground surface subsidence can be well controlled.The deformation of the envelope and the surface has a strong time effect and increases with time,in the excavation stage,pile deformation presented randomness. In the excavation stage, pile deformation presented randomness.When the excavation completed 45 days,from the top of the pile to the pile at 13m depth,the lateral volume is almost equal, and thus down to the pile end the lateral volume gradually becomes zero.
