摘要：Excavation of foundation pit is a common engineering type in urban construction. In order to reduce the impact of foundation pit excavation on the environment, its supporting form plays a decisive role. In this paper, the finite element model of the large-diameter ring beam supporting system is established, and the settlement results of the soil around the foundation pit are obtained by simulating the construction process of the foundation pit. The comparison between the numerical simulation structure and the measured data shows that they are very close. It shows that the model simulation results are accurate and the proposed large diameter ring beam support system is effective.
