    Abstract
  • Saturated soft loess is a special stratum different from collapsible loess and saturated compacted loess. In order to analyze the influence of open dewatering on the deformation of deep foundation pits in strata rich in saturated soft loess, a typical deep foundation pit in Xi'an was selected for analysis. The changes of soil physical and mechanical properties before and after dewatering were analyzed in detail, the bond strength of saturated soft loess strata before and after dewatering was discussed, and the measured and calculated values of deformation of deep foundation pits before and after dewatering were compared. The research results provide a reference for the selection of design parameters for deep foundation pits in layers rich in saturated soft loess in terms of changes in physical and mechanical properties, bond strength improvement and deformation control, and provide regional experience for similar projects.
