Abstract
In order to study the impact of pit excavation on the adjacent existing subway structure, the safety impact assessment of a project was carried out using project under construction near the subway as the engineering background. The results show that the new pit construction will produce some additional deformation on the existing subway interval structure, the deformation values are within the permissible range for safe operation. Through analysis of the results, the risk point rating of the pit adjacent to the interval is level 2. In general, the impacts of the pit construction on the neighboring subway structure are less than the specification limits.
