Abstract

To ensure the safety of deep excavations, construction is typically not allowed within a one-depth range around the excavation. In the Changsha Airport Comprehensive Transportation Hub project, the proposed West Parking Building is adjacent to an ongoing deep excavation for maglev construction, imposing constraints. To optimize the schedule, a construction plan was devised for the West Parking Building near the maglev deep excavation. Finite element analysis was employed to simulate the maglev deep excavation, assessing displacements and mechanical changes in the soil and support structures under different scenarios. The feasibility of the proximity construction plan was predicted, safety measures were proposed, and on-site implementation validated the analysis accuracy. Results indicate that, under favorable geological conditions, robust excavation support measures, and an appropriate proximity distance, the impact of proximity construction on deep excavations is minimal, rendering the plan feasible. This research provides valuable guidance for deep excavation construction.
