Abstract：Taking a deep foundation pit project in Shanghai as research background,the monitoring data collected from the retaining structures and adjacent environments during construction was analyzed.To optimize the design of the retaining structure of the foundation pit,a numerical calculation model was established by using the FLAC3d software.A comparative analysis was carried out between the monitoring data and the numerical simulation outcomes.The influence of various design parameters such as the thickness,depth,and cross-sectional dimensions of internal support of the underground diaphragm wall on the deformation of the retaining structure and the settlement of adjacent soils around the foundation pit was studied.The findings presented herein can provide valuable insights and foundational guidance for the design of retaining structures in deep foundation pit projects in soft soil terrains.
