Abstract
In the construction of foundation pit, island excavation is suitable for large-scale foundation pit because of its high speed, but it requires a higher support system. In this paper, finite element simulation is carried out for the construction process of island excavation of deep foundation pit with double-ring beam support system. The simulation process considers the construction process of island excavation and step-by-step support, and obtains the displacement field of soil around the foundation pit along with the construction progress. It provides effective guidance for the safe and smooth development of foundation pit engineering, and provides reference methods for similar engineering analysis.
