With the development of china's aboveground engineering, large cities have long been lined with high-rise buildings, and the utilization rate of above-ground space in large cities has reached a very high level, and research has gradually turned to underground foundation pit engineering to make full use of underground space. Safety issues in the project are particularly important, and whether the progress of the foundation pit project will have a greater impact on the existing building, that is, it is necessary to fully understand the foundation pit project in order to better develop the foundation pit project. In this paper, the deformation mechanism of foundation pit engineering, the adverse effects of excavation of foundation pits on adjacent buildings, the innovation of foundation pit support technology, and the prospect of foundation pit engineering technology are briefly discussed.
