Influence of deep excavations on existing subways

Deformation control is an important ring in the design of deep excavations, and it is particularly important when there are adjacent buildings (structures). Based on a deep excavation adjacent to subway station, using finite element method, a model for soil-structure interaction is established. In order to reduce the influence of excavation deformation on the subway, the relevant measures and suggestions are put forward considering the safe, economic and reasonable characteristics. It may provide a reference for similar projects.
