Abstract

The construction process of urban deep foundation pits will inevitably have an impact on nearby buildings. Taking Guangzhou Dayuan station project as the research object, this paper makes theoretical analysis by consulting a large number of data, and uses numerical simulation calculation method for image processing and simulation calculation. The deformation of surrounding buildings caused by deep foundation pit excavation is analyzed. The main contents are as follows: (1) With the help of MIDAS GTS finite element software, the numerical simulation of deep foundation pit and building pile is carried out, the image of pile foundation is processed, and the influence of deep foundation pit excavation depth on pile deformation is studied; (2) Analyze the simulated calculation data and the variation law of horizontal settlement and displacement of pile foundation; (3) Through the deformation analysis of pile foundation, the maximum settlement of pile foundation close to the foundation pit is obtained, which provides theoretical basis and engineering guidance for the design and construction of similar deep foundation pit projects.
