摘要：At present, there are more and more high-rise buildings and underground projects due to the shortage of land in the city, and a large number of deep foundation pits need to be built accordingly in order to study the impact on the surrounding environment in the process of foundation pit excavation. In this paper, the finite element method is proposed to simulate the excavation of foundation pit with large diameter ring beam support system. By simulating an example project, the step-by-step excavation and step-by-step support procedures in the construction steps are reproduced. The calculation results show that the ring beam support system avoids large stress concentration and has little impact on the surrounding environment. The successful simulation of this example provides an effective reference for finite element analysis of similar projects and an effective tool for engineering analysis.
