Based on a comprehensive office building project in Wuhan,a numerical analysis model for the impact of foundation pit excavation on surrounding buildings was established,and its accuracy was verified using on-site measured data.On this basis,the influence of factors such as excavation depth of the foundation pit,horizontal displacement of the retaining structure,and the relative position of the foundation pit and the building on the deformation of existing buildings was analyzed.A database for the deformation of existing buildings was established,and a simplified semi-empirical prediction model was established to evaluate the deformation of the buildings adjacent to the foundation pit.The accuracy of the theoretical calculation model was verified through the measured data of the existing projects.
