【 摘 要 】
In order to deeply study the influence of complex foundation pit group excavation on surrounding buildings, this paper takes concrete engineering as an example, using finite element software MIDAS GTS/NX to set up a three-dimensional deep foundation pit model for a piece of land project in a certain city, and carries out numerical simulation and analysis. This paper introduces the general situation of the project, the process of establishing the model, and the value of the deformation of the building and the supporting structure. The results show that the horizontal displacement of the same point increases gradually with the increase of the excavation depth of the foundation pit. The increase of excavation depth will also result in the maximum horizontal displacement moving gradually from the top of the slope to the middle and lower part of the deep foundation pit. In this paper, the three-dimensional numerical simulation analysis of the engineering is carried out according to the site construction procedure, in order to provide technical reference for the support selection and construction of similar projects.
