Abstract：
In recent years, with the transformation of the old business districts of the city, more and more deep foundation pit projects have appeared in the bustling area where the surrounding environment is complex. In order to ensure the stability of surrounding buildings and structures during the construction process, the internal support method and the reverse design method are widely used in the forms of engineering support. However, depending on the construction status of different projects and projects at different stages, the plan must be optimized. In this paper, combined with the foundation project of the Changsha International Finance Center project during the construction process, and according to the actual situation of the site, the design of the basement and the plan are doubled. Afterwards, the part of the basement of the podium is changed from the original scheme to the smooth and reverse combined with the construction adjustment to analyze the pros and cons.
