Abstract：

As urbanization continues to develop, foundation pit engineering, as a critical component of construction projects, is crucial for the safety and quality of the entire building project. However, traditional methods for assessing the structural stability of foundation pits suffer from issues such as isolated information and lack of dynamism. Therefore, this paper delves into the application practices of BIM 5D technology in the full life cycle evaluation of foundation pit structural stability, analyzing its technical principles, implementation processes, and application effects. The aim is to provide valuable references for improving the refined management and safety of foundation pit projects.
