Abstract: The centrifugal model tests are used to study the excavation effects of interval foundation pits on the adjacent structures and the retaining walls. The tests adopt the generalized similarity ratio of 200 to carry out the scale simulation. The foundation pits are excavated in six steps of the shutdown-excavation method. The deformation data at different positions of the station walls, the tunnel walls and the retaining walls in each step are obtained. Finally, the deformation rules of the structures close to the interval foundation pits are drawn by analyzing these data. This study may provide some reference for the design and construction of similar projects in the future.
