Design of Foundation Pit Dewatering Plan and Study on Deformation Law of Groundwater Level
Foundation pit dewatering is a key engineering problem that deep foundation pit engineering must face.This article proposes a precipitation plan based on actual foundation pit engineering,which involves rapid and large-scale drainage at the top in the early stage and stable and lightweight drainage at the bottom in the later stage.The precipitation amplitude is adjusted using a collection well.Based on the data of groundwater level changes,this precipitation plan has a higher degree of matching with the time difference of construction intensity.The results show that the foundation pit dewatering scheme can not only ensure that the groundwater level is below the construction surface of the foundation pit,but also control the dewatering rate to ensure the safety of the foundation pit slope.
