In recent years,with the rapid development of cities,there has been a significant increase in the construction activities of deep foundation pits adjacent to urban elevated bridges.The deformation of urban elevated bridges is influenced by various factors such as geological conditions of foundation pits,excavation methods,and support schemes.Based on the deep foundation pit project of a subway station in Nanjing,a three-dimensional spatial model was established to study the impact of deep foundation pit excavation on the deformation of adjacent existing municipal expressway viaducts.The calculation results were compared and analyzed with on-site monitoring data.The results showed that the enclosure scheme was reasonable and feasible,meeting the deformation control requirements during the operation of municipal expressway viaducts.The relevant achievements can serve as a reference for similar projects in the future.
