【 摘 要 】

With the development of urban construction, in order to alleviate the impact of foundation pit excavation on the surrounding environment, some complex support forms have been adopted. In order to reduce the risk of these supports, numerical method is a very effective method. In this paper, numerical analysis is carried out on the complex supporting form of a deep foundation pit. The supporting system structure is regarded as a whole structure by using the three-dimensional finite element method, and the space-time evolution law of the surrounding soil and structure during the foundation pit construction process is obtained. It provides an effective means for the analysis of complex supporting system of foundation pit.
