THE IMPACT OF DEEP FOUNDATION PIT DEWATERING ON THE FOUNDATION PIT AND SURROUNDING ENVIRONMENT
This article uses a finite element model to analyze the impact of deep foundation pit dewatering on the deformation during the construction process of a deep foundation pit under complex geological conditions.The research results indicate that the seepage effect of deep foundation pit dewatering leads to the formation of water head difference between the outside and inside of the construction site,which increases the deformation of the protective device and the effect of seepage force.As the excavation depth increases,the head difference and seepage force also increase,thereby exacerbating the impact of seepage on the deformation of the protective wall.The interaction between fluid and solid is a key factor affecting the settlement of deep foundation pits.
