摘要：With the acceleration of urbanization, more and more large-scale deep foundation pit projects are being carried out in the city. Due to the requirements of site and construction technology, it is necessary to design a supporting form that can be used as a supporting system without affecting the construction. In this paper, the large open ring beam structure is proposed as the supporting system, and the direct beam supporting system and the proposed ring beam supporting system are analyzed by finite element method. The structure shows that the ring beam structure proposed in this paper has better effect. The support form proposed in this paper provides an effective reference for design and optimization of foundation pit support form.
