Abstract

Accurate description of seepage state is the basis and premise for foundation pit groundwater control design. The water level inside and outside the foundation pit and the pore water pressure of the surrounding soil, and the rate of water inflow of foundation pit with suspended water curtain are analyzed in this paper based on the measured data. The determination of dewatering target layer and the change law of water head and pore water pressure during precipitation are summarized. It is hoped that the analysis of the successful case of groundwater control will be of some reference value to similar projects.
