【 摘 要 】

As the working conditions of foundation pit engineering become more and more complex, its requirements for supporting forms are also higher and higher. The plane excavation of a complex foundation pit in a project requires the reservation of a large plane position, a working space for machinery, and as much as possible to reduce the impact of excavation on the surrounding environment. In this paper, the support effect of the straight beam and the ring beam is simulated by finite element method according to the optimization of the straight beam form used in the design. Through comparison, it is found that the support effect of the ring beam is better. The research methods and ideas in this paper provide effective means and reference for the development of similar projects.
