Study on the Influence of Deep Foundation Pit Excavation on Existing Structures Around

For a foundation pit project, due to its large depth, complex surrounding environment and close proximity to subway tunnel, the influence of foundation pit on the surrounding existing structures needs to be considered in excavation. According to the local geological conditions and the characteristics of the foundation pit, this paper designs the foundation pit, analyzes and evaluates the impact of foundation pit excavation on the surrounding environment. This paper puts forward the timely detection of the supporting structure and the surrounding environment in the process of deep foundation pit construction and reasonable supporting and protection measures.
